Fix options flow config_entry and add pre-commit tests

- Fix XantechOptionsFlow to use self._config_entry (not self.config_entry)
  The HA OptionsFlow base class has config_entry as a property reading _config_entry
- Add test to verify config_entry is stored correctly
- Update conftest.py fixture to use MockConfigEntry for newer HA versions
- Add mypy and pytest to pre-commit hooks
- Bump pyxantech dependency to >=0.10.5 (treble command fix)
- Bump version to 0.3.1
