The `mixins.scss` file is missing from the npm package. This means it's not possible to use the package [as documented](https://github.com/ausi/cq-prolyfill/blob/master/docs/usage.md#sass-less-and-other-preprocessors). I think the problem is caused by the `files` property of [the `package.json` file](https://github.com/ausi/cq-prolyfill/blob/v0.4.0/package.json#L35-L41).
