Subject: [PATCH] Modernize packaging a bit

Adding pyproject.toml allows the package to be installed using PEP517
instead of legacy `setup.py install` method. At least pip says so in a
warning when installing without the `wheel` package available.

Change setup.py to setup.cfg (using a script[0]) because setup.py is out
of fashion these days.

Remove MANIFEST.ini since LICENSE is implied[1].
