Move basic Python configuration to the root of the repo.

After way too much trying to figure stuff out I realized: why not just put the pyproject.toml right at the root of the repo? This eliminates all the #subdirectory=... when doing pip installs and also makes setuptools-scm work right again. As a bonus, lots of tools now work without any additional configuration and we can just run them as-is.

This moves the bare minimum files needed to the repo root:

• pyproject.toml
• MANIFEST.in

and updates everything else to make that work right.
