Sort by just the C* row id by default

 - Additionally instead of setting comparator on the instance, added a compare method that takes the comparator as input.
Added support for sorting columns alphabetically.

 - In addition added support for outputting column names with the extra formatting that was done in pervious versions of Aegisthus.
Fix start position when reading compressed files.
Always preserve size when deserializing.
Add tests for reading compressed sstables.
Include the Aegisthus version in the job output.
Added an option to bundle LZ4 support.

 - running with -PbuildWithLZ4Support will include LZ4 in the hadoop jar
Fixed an error when splitting input files.

 - Added a test to force splitting input sstables.
Add back support for aegisthus.maxcolsize

 - Only added to the json output format because it does not make sense
for the SSTable output format.
