Module HashSet.Int

Specalized when key type is int, more efficient than the generic type

This module is Belt.HashSet specialized with key type to be a primitive type.

It is more efficient in general, the API is the same with Belt.HashSet except its key type is fixed, and identity is not needed(using the built-in one)

See Belt.HashSet
