Introduce `Memory` class to represent context memory #130

Closed acuarica closed 3 months ago

acuarica commented 3 months ago

Context memory is represented with a plain object. Plain objects only allows keys to be either string or Symbol. This can pose problems where memory locations are realized as bigints, needing to convert to a number to query for memory locations.

This PR introduces a Memory class to support context memory using bigint directly. Moreover, by having a unique access point for memory locations, it can be easier to invalidate certain or all locations in a given Memory.
