A HashNode is an entry in an OutlinedHashTree, holding a hash value and a collection of Successors (other HashNodes).
If a HashNode has a positive terminal value (Terminals > 0), it signifies the end of a hash sequence with that occurrence count.

The successors of this node.
We don't use DenseMap as a stable_hash value can be tombstone.
