Migrate from pyobjc to a ctypes based backend on macOS?

[samschott]

I have just stumbled upon this project and it is exactly what I have been looking for / thinking to implement myself.

However, one minor complication for adopting it on my side is the reliance on pyobjc and extension modules. If you are still maintaining the project, would you be open to migrate to a ctypes-based solution, for example using rubicon-objc? If yes, I'm happy to submit a PR.

I know that pyobjc works well, so I'm a bit hesitant to jump onto something else. But I'd happy to switch to python-only solution.

Perhaps you'd start by addition an additional config backend?
