pycocotools: Add numpy as a dependency

[AlexWaygood]

Source code here: https://github.com/cocodataset/cocoapi/tree/master/PythonAPI/pycocotools.

I'm in large part trusting that the commented-out annotations here are correct. From what I can tell from the source code, they look pretty good, but I haven't verified.

Oh, pycocotools doesn't declare numpy as a dependency. There goes that idea 🤷‍♂️

A bit of a shame.

According to mypy_primer, this change has no effect on the checked open source code. 🤖🎉

@AlexWaygood Could still be worth updating the TODOs since they're no longer blocked by #5768 . PyInstaller has a similar comment concerning modulegraph (which we opted to just partially type the vendored version instead of referencing the original package)

Weird, I just checked, this is their setup.py:
setup.py.txt

And this is their .eggs-info/requires:
requires.txt

It's because pycocotools doesn't ship wheels, and the stub-uploader is currently only able to parse wheels, not sdists: https://github.com/typeshed-internal/stub_uploader/blob/022168078ff4f6ef99fa79401fc1a98c8ad0f326/stub_uploader/metadata.py#L205-L207
