Include other icons

[szili9992]

Hey just a quick suggestion.
There's a repository that includes the google material icons but also has icons created by other artists. Seeing that google rarely adds new icons would you be willing to include these as well? It would help the community out a lot as it's updated constantly and also the artists who created those icons would benefit as well.

it could be optional so the diefferent license should not be problematic for others - but than it would be an awesome feature...
