Try out eglot for python mode

Inspired by [zamansky](https://cestlaz.github.io/post/using-emacs-74-eglot/).

There were some problems with the builtin version of `project`, I had to delete
the `elpa-ess` Debian package, because it was pulling in the builtin version of
`project` before `package.el` could set up the proper paths.  I need to
investigate how to avoid this behavior in general.
