@ashnair1 I can do this if you're busy

Appreciate it. Might be a while before I can get back to this.

Same :)

I know this is still a WIP but wanted to give intermediate feedback before you spend too long going in one direction.

Let me know if/when you want me to re-review. Otherwise I'll wait until the tests pass.

For the box format stuff, feel free to change things to match Kornia's expected format. Also see #985 for what I would like things to look like in the long-term.

RtD CI will be fixed by #1827

Coverage drop is due to buggy codecov, rerunning minimum tests should fix that.

I think there are ways that this could be improved, but not without modifying kornia itself. I actually do want to do that someday, but we may also drop kornia entirely someday and switch back to torchvision-style transforms, so I'm not trying to rock the boat. This adds a much-needed VHR-10 data module, and the parts I'm uncertain about aren't public anyway, so I say we merge this and improve transform compatibility and sample consistency in the distant future.
