upgrade usort to 1.0.2 and black to 22.3.0

[pmeier]

Compared to usort==0.6.4 which we are currently using, there are two major improvments in 1.0.0:

1. Multiple import statements that import from the same module will be merged into one.
2. Imports inside an import statement are sorted lexiographically.

For example

from foo import baz
from foo import spam, ham
from foo import bar

will be turned into

from foo import bar, baz, ham, spam

That means we need to pay even less attention to import's while reviewing and would prevent stuff like

vision/torchvision/prototype/datasets/_folder.py

Lines 5 to 6 in 582d12a

	from typing import Callable, Optional, Collection
	from typing import Union, Tuple, List, Dict, Any

Note that usort==1.0.0 is not yet released, but it is scheduled for the next weeks. I ran locally with the current preview 1.0.0rc1 and it works as expected. Since we will only touch import's, the noise on git blame is minimal.

Thanks @pmeier for the initiative.
For ref for fb employees, this is the corresponding internal post: https://fb.workplace.com/groups/pyfmt/permalink/925830131387837/

I'll have to make sure updating to 1.0 doesn't clash with the internal tooling. Since I'll be on PTO in 2 days, let's do all this next year :) ?

[NicolasHug]

After a lot of back and forth I think I finally managed to make this consistent with internal linting. There was a minor formatting bug on the internal side that was fixed as well.

The repo is quiet today so it's a good time to merge this. I'll approve and merge, if anything goes wrong by EOD I'll have time to revert. Current CI failure are unrelated

Hey @NicolasHug!

You merged this PR, but no labels were added. The list of valid labels is available at https://github.com/pytorch/vision/blob/main/.github/process_commit.py

The repo is quiet today so it's a good time to merge this.

I have my branch on proto transforms fully conflicting now )))
No worries, I'll be able to fix it

[NicolasHug]

Your best bet is probably to format with the new versions before merging with main
