I'd like to configure pyproject-fmt as formatter in Zed. Formatters in Zed need to be able to read from stdin and write to stdout. It seems pyproject-fmt can do the latter, but not the former.

Is this something you would consider adding? I can provide a PR if you'd like.

I was thinking of adding this as flag under run mode:

run mode:
   -s, --stdout          print the formatted TOML to the stdout (default: False)
   -i, --stdin           read the TOML to format from the stdin (default: False)
