chore(deps-dev): Bump black from 21.11b1 to 21.12b0

Victor Engmark requested to merge dependabot-pip-black-21.12b0 into master

Bumps black from 21.11b1 to 21.12b0.

Release notes

Sourced from black's releases.

21.12b0

Black

  • Fix determination of f-string expression spans (#2654)
  • Fix bad formatting of error messages about EOF in multi-line statements (#2343)
  • Functions and classes in blocks now have more consistent surrounding spacing (#2472)

Jupyter Notebook support

  • Cell magics are now only processed if they are known Python cell magics. Earlier, all cell magics were tokenized, leading to possible indentation errors e.g. with %%writefile. (#2630)
  • Fix assignment to environment variables in Jupyter Notebooks (#2642)

Python 3.10 support

  • Point users to using --target-version py310 if we detect 3.10-only syntax (#2668)
  • Fix match statements with open sequence subjects, like match a, b: or match a, *b: (#2639) (#2659)
  • Fix match/case statements that contain match/case soft keywords multiple times, like match re.match() (#2661)
  • Fix case statements with an inline body (#2665)
  • Fix styling of starred expressions inside match subject (#2667)
  • Fix parser error location on invalid syntax in a match statement (#2649)
  • Fix Python 3.10 support on platforms without ProcessPoolExecutor (#2631)
  • Improve parsing performance on code that uses match under --target-version py310 up to ~50% (#2670)
