Use command line params of flake8

[Xenya0815]

I execute flake8 with the command line param --max-line-length=120. It would be cool if that param is also passed to isort.

The other interesting flake8 cli param is --config. My team has linting configurations for all projects. With flake8 I can reference to that files by using the --config param. You support already a setup.cfg so it would be nice to use the same as the one, used by flake8.

@Xenya0815 hi!

Thanks for taking the time to report issues/enhancements for flake8-isort, and to actually use it! :+1:

Would you have time to provide a pull request, or do some research on which API calls one needs to do to flake8 to get that data? either of that would help a lot on creating a patch to fix it and getting it released :smiley:
