Raw css imports are not supported

[gglnx]

Hello,

we're using raw css imports (sass/libsass#754), but sass-extract fails on them, because the custom imported always adds a .scss before trying to import the file.

Error: Can not determine imported file for url 'sanitize.css/sanitize.scss' imported in src/stylesheets/main.scss

Thank you!

@jgranstrom This would be relatively easy to fix, or rather try to find the file according to the original resolve algorithm of Sass. This is described in https://jonathantneal.github.io/sass-import-resolve/#resolve-algorithm, and already implemented in sass-loader's importsToResolve(). I can contribute if needed.
