more sophisticated type checking with numpy

[dcherian]

What is your issue?

This cool blogpost points out many improvements in numpy typing (NumType).

It also mentions stubtest which should be useful for our stubs, and also seems to be opt-in.

This would be a nice project for someone interested in type safety.

I’d like to start some initial investigation into this. If anyone else is interested in contributing or has specific ideas on the implementation, please let me know here! I’m happy to collaborate or step aside if someone else is already further along.
