Issue DM-4185: Experiment with c-style arrays for secondary index
Use simple C-style array (chunk[objID], allocated up to maximum number of objectIDs), or a single-layer set of arrays (chunk[block][objID%blksize], where second index runs from 0 to size of each block) to store index compactly and provide minimum overhead for lookups.
