I'd add the 3.10 Trove classifier, but where are they defined?

https://pypi.org/project/pytest-watcher/

3.6 should be in the list according to README.md and tox.ini.

@hugovk Thank you for taking your time to contribute. I was quite busy lately on my daily job and didn't have much time for open source projects.

Speaking of Python versions classifiers, according to Poetry documentation here, they should be added automatically based on Python versions specified in pyproject.toml. I just released a new version, but for some reason it didn't add 3.10 record yet. Probably I will need to investigate it a little bit more.

UPDATE:
Turned out missing Python3.10 identifier was a Poetry issue. I updated the poetry version on my system and managed to build with proper classifiers
