Black configuration in pyproject.toml

[szmazurek]

Is your feature request related to a problem? Please describe.

Black formatter will by default use a trailing comma as a newline indicator, even if the line length is still within given range. This often unnecesairly causes line to be fragmented.

Describe the solution you'd like

Add a flag in .toml file to do not split by the trailing comma by default

Describe alternatives you've considered

Setting it manually in the IDE or pssing an extra flag when calling from CMD.

Additional context

In the case of VSCode one proabably will still have to add this option in the extension config, even when the .toml file will contain it during installation.
