Would you be open to using zheller/flake8-quotes#111 as a patch here instead of limiting the flake8 version? If so, I'd be happy to create a PR.

I was hoping that PR would get a quick review and merge for a new version.

Since the PR is small and looks like the correct migration, I'm open to merging it.
