Switch to GH actions (#361)

* Switch to GH actions

Removes the travis config and adds a GH actions config. Resolves #360.

As part of this:

- only runs the README check once, instead of for each python version
- only runs mypy once, removing it from tox
- unifies the pypy and cpython tests in tox by separating dev and test
  requirements, and only installing the latter for running tests in tox

* Update README w/badge & link to GH actions tests
