Summary

Use the original pycocotools PyPI package, since pycocotools-windows does not have wheels for Python 3.9+. pycocotools doesn't have wheels either, but at least it's buildable from source.

Being notified about the appearance of binary packages in PyPI. I don't know how to describe it more precisely.
