Thanks for reviewing — I should probably either finish this or merge it, sorry for leaving it hanging for so long...

Note to future self (or if someone else finishes this) — we should add the ability to use maturin develop, since that installs the python package in a single step.

CI etc uses maturin build + pip install, which is a more complete installation path and better simulates how it'll be used, but requires an extra step + a path change
