Make babel-plugin-react-css-modules work with commonjs require

Hello,

when requiring scss files using `require()` syntax I get `Cannot use styleName attribute without importing at least one stylesheet.`. However if I switch to using import it works (minus an eslint parsing error).

I'm trying to introduce css-modules into an old code base. I have the es6 babel preset running (that's why imports work), but code is linted without modules support and I would love to keep it that way for the time being. Is there anyway to make this plugin work with require?
