*Hashmap implementation that dynamically switches from a vector based backend to a hashbrown based backend as the number of keys grows *
Halfbrown, is a hashmap implementation that uses two backends to optimize for different cernairos:
For less then 64 key value pairs it uses a dumb vector based map implementation. This trades the need to iterator through the vector for not having to hash strings on lookup or inserts.
For more then 64 elements it upgrades the map to aq hashbrown base map to account for longer itteration times.
