Implement client wrapper for MapeoManager with IPC communication

[achou11]

Description

Putting this here for now as whatever implementation we decide on will probably require changes in this repo. The primary challenge when attempting to use this in our client app code (whether it's React Native via Nodejs Mobile, or Electron) is to expose the individual project instance's API to the frontend client via rpc-reflector. rpc-reflector can't transfer an instance and so what we'll need to do is figure out the best way of designing the solution such that when creating the project instance, we create a "wrapped" instance that uses the relevant IPC channel to transfer the object and its API to the frontend.

This may end up being a separate module but even if that's the case, I suspect some work will need to be done here in order to enable that.
