Adding `wheel` to the Python development environment

[cnpryer]

I had some trouble with my environment (macos). Running cargo test resulted in the following failures

Processing /Users/chrispryer/Library/Caches/monotrail/artifacts/cffi/1.15.1/cffi-1.15.1.tar.gz

My environment required pip install wheel in order to get the tests working with Python 3.8.15.

I purged my environment and tried again with Python 3.8.15 as-is. I was confused why I needed wheel in 3.8. It works.
