Upgrade to µsort 1.0.0rc1, and apply formatting changes

[amyreese]

Summary

Upgraded µsort and µfmt in requirements. Ran ufmt format *.

Test Plan

Manual diff inspection and CI

[amyreese]

Looks like this could/should be reported as a bug on µfmt for not detecting/telling black that it's formatting a type stub.

@zsol I don't see any excludes configured in pyproject.toml, but you mentioned them on facebook/usort#62; are those needed to get a clean CI pass?

[zsol]

Ah, I had to add them in the rust branch over here: https://github.com/zsol/LibCST/blob/parser/pyproject.toml#L5-L6

There are some relevant changes you'll need to do from zsol@6925202 to get the failing tests to pass. Check out test_codegen_clean.py in that commit. Unfortunately ufmt will not run on files that end in .deleteme so the tests will always compare unformatted generated code with the formatted checked-in version. That took me a while to track down.
