pre-commit hooks

Howdy ,

great to see that the project is picking up steam again. Im sending my love from the Django community, will update to the latest release again.

Now I have been quietly working on JavaScript version of pyupdate recently called esupgrade. Since I know that @kevin-brown is a fellow Python person too, this probably is a very familiar concept.

Since I maintain Django-Select2 I frequently used this repos code for real word testing and hardening.

Finally, I think I have reached a point where I am happy. As a side effect I am sitting on a mountain of non-breaking code updates for this repo.

Are you interested in me sharing those?

I would also offer to setup a more sophisticated pre-commit suite, which might help to streamline future maintenance of this repo. Especially with pre-commit.ci giving new contributors a lift.

But that's always personal preference.

Cheers -Joe
