Persist legacy LatestPairs for now (#13378)
We added compression to the latest/first pair storage, but
the code change was forcing new things to be persisted
with the new format, meaning that any segment created with
the new code cannot be read by the old code.  Instead, we
need to default to creating the old format and then remove that default in a future version.

Modular Calcite Test Framework (#12965)
* Refactor Calcite test "framework" for planner tests

Refactors the current Calcite tests to make it a bit easier
to adjust the set of runtime objects used within a test.

* Move data creation out of CalciteTests into TestDataBuilder
* Move "framework" creation out of CalciteTests into
  a QueryFramework
* Move injector-dependent functions from CalciteTests
  into QueryFrameworkUtils
* Wrapper around the planner factory, etc. to allow
  customization.
* Bulk of the "framework" created once per class rather
  than once per test.
* Refactor tests to use a test builder
* Change all testQuery() methods to use the test builder.
Move test execution & verification into a test runner.

CompressedBigDecimal Min/Max (#13141)
This adds min/max functions for CompressedBigDecimal. It exposes these
functions via sql (BIG_MAX, BIG_MIN--see the SqlAggFunction
implementations).

It also includes various bug fixes and cleanup to the original
CompressedBigDecimal code include the AggregatorFactories. Various null
handling was improved.

Additional test cases were added for both new and existing code
including a base test case for AggregationFactories. Other tests common
across sum,min,max may be refactored also to share the varoius cases in
the future.

Add BIG_SUM SQL function (#13102)
This adds a sql function, "BIG_SUM", that uses
CompressedBigDecimal to do a sum. Other misc changes:

1. handle NumberFormatExceptions when parsing a string (default to set
   to 0, configurable in agg factory to be strict and throw on error)
2. format pom file (whitespace) + add dependency
3. scaleUp -> scale and always require scale as a parameter

Optimize CompressedBigDecimal compareTo() (#13086)
Optimizes the compareTo() function in
CompressedBigDecimal. It directly compares the int[] rather than
creating BigDecimal objects and using its compareTo.

It handles unequal sized CBDs, but does require
the scales to match.

Compressed Big Decimal Cleanup and Extension (#13048)
1. remove unnecessary generic type from CompressedBigDecimal
2. support Number input types
3. support aggregator reading supported input types directly (uningested
   data)
4. fix scaling bug in buffer aggregator

compressed big decimal - module (#10705)
Compressed Big Decimal is an extension which provides support for 
Mutable big decimal value that can be used to accumulate values 
without losing precision or reallocating memory. This type helps in 
absolute precision arithmetic on large numbers in applications, 
where greater level of accuracy is required, such as financial 
applications, currency based transactions. This helps avoid rounding 
issues where in potentially large amount of money can be lost.

Accumulation requires that the two numbers have the same scale, 
but does not require that they are of the same size. If the value 
being accumulated has a larger underlying array than this value 
(the result), then the higher order bits are dropped, similar to what 
happens when adding a long to an int and storing the result in an 
int. A compressed big decimal that holds its data with an embedded 
array.

Compressed big decimal is an absolute number based complex type 
based on big decimal in Java. This supports all the functionalities 
supported by Java Big Decimal. Java Big Decimal is not mutable in 
order to avoid big garbage collection issues. Compressed big decimal 
is needed to mutate the value in the accumulator.
