Get on the PEP 517 train.

• After this a project might not have a setup.py file.
• The build backend and configuration happen in the pyproject.toml file.
• See also https://pypa-build.readthedocs.io/en/latest/

Impacts on release-actions:

• Cannot extract version from setup.py file, not sure if setuptools has a nice interface for extracting this.
• Projects can configure what gets built.
• The build command changes to python -m build.
