Why?

We've been having CI failures (such as this) because we're using a deprecated approach to building python packages (calling python setup.py) and trying to target a deprecated format (eggs). Rather than figure out exactly what broke, I've swapped us to using build, the current industry standard in favor of setuptools.

Separately, I added better logging to our dependency installation when running in CI, which will help us understand better why something might have broken.

Note: this has no user-facing impact. We're just building our package for distribution in a more modern way.

What?

• swap python setup.py call to python -m build
• swap setuptools dependency for build
• add more logging to dependency installation when running in CI.
