Commit Message

[IMPROVED] NumPending calculations and subject index memory in filestore (#4960)

Swapped out psim as a go hashmap for our stree implementation.

Stree is an adaptive radix tree implementation used for storing and
retrieving literal subjects. It also allows quick matching to wildcard
subjects, which is it's major design goal along with using less memory
in high subject cardinality situations.

This will be used in the filestore implementation to replace the PSIM
hash map which was fast at insert and lookup but suffered when trying to
filter based on wildcard subjects.

This is used specifically in calculations on NumPending with a wildcard,
and given we push folks to use larger muxed streams with down filtered
consumers and/or mirrors this was becoming a performance issue.
