make a style configuration alias compatible with isort & black?

I am using importmagic with emacs, and thank you for writing this library and allowing me to gradually flee the slowly crumbling edifice of Pymacs and Rope. (No disrespect to to the maintainers of those venerable libraries, I hope that they get the upgrades that they need, but as a user they've been lagging somewhat and I don't have the energy to invest to maintain them myself.)

However, when importmagic reformats my imports it does the wrong thing on projects that already have auto-formatting with isort and black. This isn't a big deal, as CI and commit hooks catch the problems and fix them up, but it would be nice for everything to happen automatically.
