  1. Add in support for segmented binary stream snapshots. 

    Streams with many interior deletes was causing issues due to the fact that the interior deletes were represented as a sorted []uint64.
This approach introduces 3 sub types of delete blocks, avl bitmask tree, a run length encoding, and the legacy format above.
We also take into account large interior deletes such that on receiving a snapshot we can skip things we already know about.
