Shapely doesn't have a Windows wheel on pypi yet, but we can get them
from https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely. This unblocks
(and because wheels are matched to python versions, *requires*)
upgrading to Python 3.10.
GitHub has limits on the number of files that can be used with
upload-artifact, and it sounds like it will also be faster to compress
locally before uploading.
The upload-artifact version 2.3 has problems with 0byte files and prevent the build action from beeing completed.
This temporary fix should be reverted when they fixed the bug.
This appears to be incompatible with pyinstaller. I get the following
when trying to run the executable generated with pyside6:
```

* Use TACAN channels more selectively
* Increase tacan range to 126
* Use pytest and add workflow
* Skip faction tests due to outdated test data
* Run mypy on tests directory also
* Use iterators for bands AND usages, add tests
py is a shortcut that launches the *latest* version of Python on the
machine. https://stackoverflow.com/a/50896577/632035
The build machines were updated to include python 3.9, so we were
doing everything with 3.9 instead of 3.8. pyproj doesn't have a binary
wheel for 3.9 on pypi yet, so we were falling back to building it from
source, which we aren't able to do, breaking the build.
