Subject: [PATCH] Remove support for Python 2
I noticed that a number of the scripts in `contrib/` were Python-2-only,
so I did a basic untested port of those while I was here.
Apply pyupgrade --py3-plus
Simplify coverage testing
We no longer need the more complex arrangements after dropping Python 2
support.
