Plan for migrating the stubs to NumPy

[person142]

These are the things I'm planning on doing to merge the stubs into NumPy:

• Get MAINT: Fix issue 77: Don't allow initializing generic #80 merged
• Move the tests to NumPy. That way we can keep running them during the migration.
• Add the new numpy.typing module
• Move all the stubs over
• Get the tests hooked up to CI

Please raise any concerns here.

Well, no plan survives contact with the enemy, and it turned out to be hard to port the tests and stubs separately... so I did them both at the same time: numpy/numpy#16515

Still need to add the typing module at runtime, but by and large... migration complete!

Awesome, thanks @person142 and everyone else who contributed!
