py-black: updated to 23.9.1

23.9.1

Due to various issues, the previous release (23.9.0) did not include compiled mypyc
wheels, which make Black significantly faster. These issues have now been fixed, and
this release should come with compiled wheels once again.

There will be no wheels for Python 3.12 due to a bug in mypyc. We will provide 3.12
wheels in a future release as soon as the mypyc bug is fixed.

Packaging

- Upgrade to mypy 1.5.1

Performance

- Store raw tuples instead of NamedTuples in Black's cache, improving performance and
 decreasing the size of the cache

23.9.0

Preview style

- More concise formatting for dummy implementations
- In stub files, add a blank line between a statement with a body (e.g an
 `if sys.version_info > (3, x):`) and a function definition on the same level
- Fix a bug whereby spaces were removed from walrus operators within subscript

Configuration

- Black now applies exclusion and ignore logic before resolving symlinks

Performance

- Avoid importing `IPython` if notebook cells do not contain magics
- Improve caching by comparing file hashes as fallback for mtime and size

_Blackd_

- Fix an issue in `blackd` with single character input

Integrations

- Black now has an
 [official pre-commit mirror](https://github.com/psf/black-pre-commit-mirror). \ 
Swapping
 `https://github.com/psf/black` to \ 
`https://github.com/psf/black-pre-commit-mirror` in
 your `.pre-commit-config.yaml` will make Black about 2x faster
- The `.black.env` folder specified by `ENV_PATH` will now be removed on the \ 
completion
 of the GitHub Action
