The plugin now supports Python 3.7 and 3.8. This is useful if:
- your CI pipeline runs on Python 3.7 or 3.8 for some reason, but the project is on 3.9+
- you're using `from __future__ import annotations`
Python 3.7.x and 3.8.x behaviour is configurable:
flake8-pep585:
--pep585-activation {auto,always,never}
Whether to enable plugin on Python 3.7 and 3.8 (always),
only enable if 'from __future__ import annotations'
is present (auto, default) or disable (never)
Thanks to plinss for implementing this!
