The new type get influentiated by the ObjectsMap impl on backend
code but with simplier implementation that no longer restricts keys
to UUID type but preserves the same performance characteristics.
This type encodes and decodes correctly both in fressian (backend)
and transit (backend and frontend).
This is an initial implementation and several memory usage
optimizations are still missing.
That replaces the ad-hoc helpers for convert path content from
plain with encapsulated type that implements the appropriate
clojure protocols and interfaces that helps interacting with
binary encoded path data
