distutils is gone with new Python

• remove setup.py
• update [build-system] section of pyproject.toml (see diversity repo)
• dynamic dependencies from file not working, hard-code like in diversity That should do it

Currently pip -e ".[dev]" and then pytest gives no warning on my Mac with the following active:

• Python version 3.11.0
• pip 22.3 This will not do; need to support Python 3.12 at least.
