Hi @hantmac - I'm so sorry for dropping the ball on this PR. I've merged master on it to restart CI, and will re-review and merge if everything is ok today

[villebro]

LGTM, thanks for the fantastic quality of this PR (tests, docs etc) ❤️

@hantmac it seems there's quite a few linting errors here:

Would you be able to resolve them? If not I can pick this up and push it through next week.

Could you use superset.constants.TimeGrain?

TimeGrain.MINUTE: "to_start_of_minute(TO_DATETIME({col}))",
