omegaga	d51dc96a79	Experiments on column-aware encodings ... Summary: Experiments on column-aware encodings. Supported features: 1) extract data blocks from SST file and encode with specified encodings; 2) Decode encoded data back into row format; 3) Directly extract data blocks and write in row format (without prefix encoding); 4) Get column distribution statistics for column format; 5) Dump data blocks separated by columns in human-readable format. There is still on-going work on this diff. More refactoring is necessary. Test Plan: Wrote tests in `column_aware_encoding_test.cc`. More tests should be added.
