Replace String/byte[] with (N)IO streams (#838) 

Closes #837 

Replaced raw `String` and `byte[]` usages with `CharSequence`, `InputStream`/`OutputStream` and `CharBuffer`/`ByteBuffer` concepts where possible to eliminate unnecessary creation of intermediate byte arrays and/or temporary Strings.

-----
- Changed TokenizedJwt and TokenizedJwe interfaces and implementations to return CharSequences instead of Strings to avoid creating new Strings on the heap
- Changed internal Base64 implementation to work with a CharSequence instead of a raw char[] to reduce need to create new arrays on the heap
- Changed Base64Decoder generics signature from Decoder<String,byte[]> to Decoder<CharSequence,byte[]>
- Decoders.BASE64 and Decoders.BASE64URL now reflect Decoder<CharSequence,byte[]>
- Changed Strings#utf8 implementation to accept a CharSequence instead of a String
- Added new Strings#wrap to wrap a CharSequence into a CharBuffer if necessary
- Renamed not-yet-released JwtBuilder#serializer method with JwtBuilder#json
- Renamed not-yet-released JwtParserBuilder#deserializer method with JwtParserBuilder#json

-----
- Moved JwtDeserializer from io.jsonwebtoken.impl to io.jsonwebtoken.impl.io package, created two new subclass implementations for use with Jwks and JwkSets
- Renamed JwtDeserializer to JsonObjectDeserializer that defaults to throwing MalformedJwtException.  Added two subclasses, JwkDeserializer and JwkSetDeserializer that throws JWK and JWK Set-specific exceptions.

-----
Changed ParserBuilder#deserializer method name to ParserBuilder#jsonReader

-----
Removed all usages of Serializer#serialize and Deserializer#deserialize except for deprecated implementations.  All other usages now use InputStream/OutputStream concepts

-----
Added Jwks#json and Jwks#UNSAFE_JSON for assistance in serializing JWKs to JSON (test cases, README examples, etc)

-----
- Ensured Encoder and CompressionAlgorithm supported streams instead of just byte arrays
- Copied over necessary (Apache-licensed) code from Apache commons-codec to obtain Base64OutputStream and Base64InputStream capability for efficient encoding during compact JWT creation.  Hopefully this is temporary and we can strip out most if not all of this and modify our existing Base64.java class for simpler support since we have many less use cases than what commons-codec supports.  All implementations are now in the `impl` module only.

-----
Converted all DigestAlgorithms to utilize an InputStream for data instead of byte[]

-----
- Added JwtBuilder InputStream payload support: added JwtBuilder#content(InputStream), JwtBuilder#content(InputStream, String contentType), JwtBuilder#content(String, String contentType)
- Added CountingInputStream as a way to check and assert that b64/unencoded payload InputStreams cannot be empty.

------
Renamed Encoder/Decoder and CompressionAlgorithm 'wrap' methods to encode/decode/compress/decompress for better readability and to make clearer the intent of the method. Also to avoid name/text/search collisions with 'wrap' references.

-----
Renamed new JwtBuilder#encoder and JwtParserBuilder#decoder methods to JwtBuilder#b64Url and JwtParserBuilder#b64Url for shorter method chains

-----
- Updated AeadAlgorithm and its AeadRequest/AeadResult concepts to utilize Input/Output Streams
- Renamed InitializationVectorSupplier to IvSupplier (was verbose, and it's a new interface, and it's not commonly referenced in the API, so the extra verbosity isn't needed)

* Provides Base64 encoding and decoding as defined by <a href="http://www.ietf.org/rfc/rfc2045.txt">RFC 2045</a>.

* This class implements section <cite>6.8. Base64 Content-Transfer-Encoding</cite> from RFC 2045 <cite>Multipurpose
* Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies</cite> by Freed and Borenstein.
* </p>
* <p>
* The class can be parameterized in the following manner with various constructors:
* </p>
* <ul>
* <li>URL-safe mode: Default off.</li>
* <li>Line length: Default 76. Line length that aren't multiples of 4 will still essentially end up being multiples of
* 4 in the encoded data.
* <li>Line separator: Default is CRLF ("\r\n")</li>
* </ul>
* <p>
* The URL-safe parameter is only applied to encode operations. Decoding seamlessly handles both modes.
* </p>
* <p>
* Since this class operates directly on byte streams, and not character streams, it is hard-coded to only
* encode/decode character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252,
* UTF-8, etc).
* </p>

Rationale for while-loop on (readLen == 0):
-----
Base32.readResults() usually returns > 0 or EOF (-1). In the
rare case where it returns 0, we just keep trying.
This is essentially an undocumented contract for InputStream
implementors that want their code to work properly with
java.io.InputStreamReader, since the latter hates it when
InputStream.read(byte[]) returns a zero. Unfortunately our
readResults() call must return 0 if a large amount of the data
being decoded was non-base32, so this while-loop enables proper
interop with InputStreamReader for that scenario.

This is a fix for CODEC-101
