Gazelle

[stevemer]

This project doesn't seem to support Python gazelle rules. Are you planning to add them?

Check out #24 - I implemented this but in practice I found I didn't like some of the limitations I found in rules_py+gazelle.

I don't plan to land this PR, but it should apply cleanly at the head of main right now if you want to use it in a fork of your own
