py-test-rerunfailures: updated to 9.1.1

9.1.1

Compatibility fix.
- Ignore ``--result-log`` command line option when used together with ``pytest
  >= 6.1.0``, as it was removed there. This is a quick fix, use an older
  version of pytest, if you want to keep this feature for now.
- Support up to pytest 6.1.0.

9.1

Features
- Add a new flag ``--only-rerun`` to allow for users to rerun only certain
  errors.

Other changes
- Drop dependency on ``mock``.
- Add support for pre-commit and add a linting tox target.
