cf4297a771 Optimize TopN() w/ source query. 
This commit makes several changes to optimize the TopN() query:

- Reduce highbits() back from 24-bits to 16-bits.
- Reduce MaxArraySize back from 2^20 to 4096.
- Optimize bitmap count invalidation.
- Parallelize TopN() across nodes.
- Parallelize TopN() across slices.

08659c350b optimize intersection count 
This commit moves the computation of the intersection count to
the `roaring` package so that no allocations are required. The
implementation operates at the roaring container level and has
specialized functions for array-array, array-bitmap, and
bitmap-bitmap container pairs.
