[SYSTEMDS-3574] Recompress Compressed Matrix

This commit adds support to recompress a compressed matrix
via the standard compression plan of extracting statistics from groups,
and using these in the sequence of co-coding and applying the co-coding
plan to the compressed column groups via the CLALibCombineGroups.

The implementation currently is naive in the sense that it does not
guarantee that the output column groups are of the type expected and wanted
since the combine algorithms are simplified to only return groups that
made it easy to combine not enabling a specific plan to be followed.

Closes #1836
