Contribute document icons

[casouri]

I got some document icons here: https://github.com/casouri/emacs-file-icon

I wonder how can I add them to your collection?

Thanks 😄

Makes me wonder if there is a Awesome Emacs project and if these two projects should just appear in that list in the same categories

@agsdot @kuanyui ?

I think a new category on awesome-emacs is needed for icons...

Feel free to contribute a PR as long as you like.
