Immutables (#790) 

* Jwts#header() and JwtBuilder#header() API cleanup

* added license headers, removed unused Conjunctor interface concept

* impl checkpoint for Registry-to-Map implementation change

* Jwts.SIG and Jwts.ENC conversion checkpoint (complete)

* Jwts.KEY and Jwks.HASH conversion checkpoint (complete)

* File header and Javadoc cleanup.  Removed unused SignatureRequest.java concept.

* Changed deprecated API usage in test case

* - Removed *Accessor concepts where possible, just using the *Header interfaces was sufficient
- KeyAlgorithm#getEncryptionKey now accepts a JweHeader that is mutable. Implementations can just use Map#put to modify the header state if desired.

* MapMutator method renaming to avoid odd conventions

* introduced ProtectedJwt concept and intermediate DefaultProtectedJwt implementation

* Removed all usages of CompressionCodecs.java in favor of a new Jwts.ZIP entry.
Renamed all Standard***AlgorithmsBridge to Standard***Algorithms

* CompressionCodec to CompressionAlgorithm transition (complete, code coverage 100%)

The `io.jsonwebtoken.SignatureAlgorithm` enum has been deprecated in favor of new
`io.jsonwebtoken.security.SecureDigestAlgorithm`, `io.jsonwebtoken.security.MacAlgorithm`, and
`io.jsonwebtoken.security.SignatureAlgorithm` interfaces to allow custom algorithm implementations. The new
`SIG` constant in the `Jwts` helper class is a registry of all standard JWS algorithms as expected, exactly like the
`io.jsonwebtoken.security.SignatureAlgorithm` interfaces to allow custom algorithm implementations. The new nested
`Jwts.SIG` static inner class is a registry of all standard JWS algorithms as expected, exactly like the
old enum. This change was made because enums are a static concept by design and cannot
support custom values: those who wanted to use custom signature algorithms could not do so until now. The new
interface now allows anyone to plug in and support custom algorithms with JJWT as desired.

Now that the JWE and JWK specifications are implemented, only a few things remain for JJWT to be considered at
version 1.0. We have been waiting to apply the 1.0 release version number until the entire set of JWT specifications
are fully supported and we drop JDK 7 support (to allow users to use JDK 8 APIs). To that end, we have had to
deprecate some concepts, or in some rare cases, completely break backwards compatibility to ensure the transition to
1.0 (and JDK 8 APIs) are possible. Any backwards-incompatible changes are listed in the next section below.

deprecate some concepts, or in some cases, completely break backwards compatibility to ensure the transition to
1.0 (and JDK 8 APIs) are possible. Most backwards-incompatible changes are listed in the next section below.
#### Backwards Compatibility Breaking Changes, Warnings and Deprecations
* `io.jsonwebtoken.Jwts`'s `header(Map)`, `jwsHeader()` and `jwsHeader(Map)` methods have been deprecated in favor
of the new `header()` builder-based method to support method chaining and dynamic Header type creation.
* `io.jsonwebtoken.Jwt`'s `getBody()` method has been deprecated in favor of a new `getPayload()` method to
reflect correct JWT specification nomenclature/taxonomy.
* `io.jsonwebtoken.Jws`'s `getSignature()` method has been deprecated in favor of a new `getDigest()` method to
support expected congruent behavior with `Jwe` instances (both have digests).
* `io.jsonwebtoken.CompressionCodec` now inherits a new `io.jsonwebtoken.Identifiable` interface and its `getId()`
method is preferred over the now-deprecated `getAlgorithmName()` method. This is to guarantee API congruence with
all other JWT-identifiable algorithm names that can be set as a header value.
* `io.jsonwebtoken.Header` has been changed to accept a type-parameter for sub-type method return values, i.e.
`io.jsonwebtoken.Header<T extends Header>` and a new `io.jsonwebtoken.UnprotectedHeader` interface has been
introduced to represent the concrete type of header without integrity protection. This new `UnprotectedHeader` is
to be used where the previous generic `Header` (non-`JweHeader` and non-`JwsHeader`) interface was used.
* Accordingly, the `Jwts.header()` and `Jwts.header(Map<String,?>)` now return instances of `UnprotectedHeader` instead
of just `Header`.
#### Breaking Changes
* `io.jsonwebtoken.Jwts`'s `header(Map)`, `jwsHeader()` and `jwsHeader(Map)` methods have been removed in favor
of the new `header()` builder-based method to support method chaining and dynamic Header type creation.
* **JWTs that do not contain JSON Claims now have a payload type of `byte[]` instead of `String`** (that is,
`Jwt<byte[]>` instead of `Jwt<String>`). This is because JWTs, especially when used with the
`cty` (Content Type) header, are capable of handling _any_ type of payload, not just Strings. The previous JJWT

* `io.jsonwebtoken.SigningKeyResolver`'s `resolveSigningKey(JwsHeader, String)` method has been changed to
`resolveSigningKey(JwsHeader, byte[])`.
* `io.jsonwebtoken.Jwts`'s `parser()` method deprecated 4 years ago has been renamed to `legacyParser()` to
allow an updated `parser()` method to return a `JwtParserBuilder` instead of a direct `JwtParser` instance.
This `legacyParser()` method will be removed entirely for the 1.0 release - please change your code to use the
updated `parser()` method that returns a builder as soon as possible.
* `io.jsonwebtoken.Jwts`'s `header()` method has been renamed to `unprotectedHeader()` to allow a newer/updated
`header()` method to return a `DynamicHeaderBuilder` instead of a direct `Header` instance. This new method /
return value is the recommended approach for building headers, as it will dynamically create an `UnprotectedHeader`,
`JwsHeader` or `JweHeader` automatically based on builder state.
* **`io.jsonwebtoken.Claims` and `io.jsonwebtoken.Header` instances are now immutable** to enhance security and thread
safety. Creation and mutation are supported with newly introduced `ClaimsBuilder` and `HeaderBuilder` concepts.
* `io.jsonwebtoken.Jwts`'s `headerBuilder()` method has been renamed to `header()` and returns a
`DynamicHeaderBuilder` instead of a direct `Header` instance. This builder method is the recommended approach
for building headers in the future, as it will dynamically create an `UnprotectedHeader`, `JwsHeader` or `JweHeader`
* Consequently, `io.jsonwebtoken.Jwts`'s `claims()` static method has been changed to return a `ClaimsBuilder` instead
of a `Claims` instance.
* Similarly, `io.jsonwebtoken.Jwts`'s `header()` static method has been changed to return a `HeaderBuilder` instead of
a `Header` instance. The `HeaderBuilder` will dynamically create a `Header`, `JwsHeader` or `JweHeader`
automatically based on builder state.
* `io.jsonwebtoken.Jwts`'s `header()` method now returns a `DynamicHeaderBuilder` instead of a
direct `Header` instance. This new method / return value is the recommended approach for building headers
in the future, as it will dynamically create an `UnprotectedHeader`, `JwsHeader` or `JweHeader` automatically
based on builder state.
* `io.jsonwebtoken.Jwts`'s `parser()` method deprecated 4 years ago has been changed to now return a
`JwtParserBuilder` instead of a direct `JwtParser` instance.
* `io.jsonwebtoken.CompressionCodec` implementations are no longer discoverable via `java.util.ServiceLoader` due to
runtime performance problems with the JDK's `ServiceLoader` implementation per
https://github.com/jwtk/jjwt/issues/648.
