[SYSTEMDS-373] Fix error in new compression

Remove Quan ColGroup because of new Dictionary technique.

- FIX Quantile and CentralMoment for DDC ColGroups
- compression tests remove redundant tests in Par Compressed Matrix and
  Remove dependency on AutomatedTestBase
- Compare matrix now only count the first 50 discrepancies
- Rounding improvement in Quantized representation
- Out commented some debugging
- Fix count distinct compressed test works, but is not comparable
  to count distinct non lossy. since the number of distinct values
  can both grow and shrink
- Update Dictionary to not copy a copy for lossy dictionaries on scalar
  operations
- Dictionary constructor in all colGroups
- QDictionary Optimize scalar operator
- Improve scalar operation
- Fix leftMultByRowVector OLE in case of only one value!
- Improve ColSum
- Improvements in performance of unary aggregates
- ColGroupValue fix for single column colGroups
- disallowing ColGroup construction with double array
- Dictionary documentation
- Fixed docs for ColGroupValue
- Lossy Bitmap fix and improved performance
- revert DMLScript entry file
- call BitMap lossy for 8Bit bitmap
- DDC rework, moving dublicate code to DDC from DDC1 and 2,
  furthermore general fixes and optimizations in tests and
  all ColGroups for better lossy handling
- DDC docs fix
- common sum and ColSum without performance degradation
- Fix bug in Unary aggregate where output from uncompressed ColGroup was
  empty
- Move SkipList boolean to compression Settings
- Dictionary correcting Override keyword
- A dictionary not I Dictionary
- in sum all rows to Double dictionary always reuse double array
- Allowing more tests to execute. Compression
- Parallel scalar operations
- shallow serialize
- rename AbstractBitmap to ABitmap
