When installing via NPM, sanatize.css dependency is missing

[kevinriemens]

Perhaps put it in as a peer dependency?
Out of the box, it breaks an angular 6 apllication build because of the missing depedency.

It's an easy fix, but perhaps a good addition to the project, to add it as a peer depedency in the package.json.

I ran npm install --save-dev sanitize.css@5.0.0

And in marx.scss, I had to change:

@import '../node_modules/sanitize.css/sanitize';

to:

@import '../../sanitize.css/sanitize';
