Configure pyproject-fmt options from pyproject.toml file #130

I would like to be able to set the pyproject-fmt command line arguments via a specification in the pyproject.toml file itself. Namely, I want to be able to set the indent default from within the pyproject.toml, so that the tool can be run independently of pre-commit with a indent=4. I have to support devs who prefer to independently run all the tooling checks specified within the .pre-commit-config.yaml, so I would like to be able to specify the configuration outside of specifying arguments to be passed via the .pre-commit-config.yaml file.
