Hi yt team !
Chris implemented a long requested API for swapping/flipping plot axis in https://github.com/yt-project/yt/pull/3640

I wanted to bring your attention to it because the patch, while moderately substantial, is likely intimidating to reviewers.
I just gave my own approval after months of back and forth with Chris, and I believe the implementation is now robust enough for inclusion.

I believe the API is mostly uncontroversial, _except_ for one aspect that we want to resolve before the next feature release, and for which a discussion is open, see
https://github.com/yt-project/yt/issues/3890

If we can’t find another reviewer, and if no one objects, I would like to merge this PR in a week or so, so we can move on to resolve the remaining question as a separate, second step.

Please let us know if you have any concerns with the PR, if you would like some more time to review it, or if you object having it merged with just my approval.

Take care
Clément
