[SYSTEMDS-3478] Bitset array for Frames
This commit adds a BitSetArray primitive as alternative to BooleanArray
for frames. As example on a 64kx2k frame with booleans:
- write time improved from 0.3-0.6 to 0.162
- read time improved from 0.4 to 0.119
- size on disk and memory from 128MB to 16MB
Closes #1750
