Wheels for 3.9 and 3.10

Is it possible to release wheels for CPython 3.9 and 3.10 to PyPi? This project looks really cool, but I'd rather not have to install rust and build this in CI, as that would slow down building and testing considerably. I checked the code for instructions on how to build wheels, but I couldn't find any. I'd also like to try contributing to the code, but I don't see any standards for contributing. Should I use rust-fmt? Are there any quirks to know about before I start trying to contribute?
