Icon Request: fa-snowdrift
I request the addition of the [Snowdrift.coop](https://snowdrift.coop) icon.

### common usecase:
project websites having some sort of link to their snowdrift.coop page.


> As SVG isn't an allowed attachement format [I zipped up the plain logo](https://github.com/ForkAwesome/Fork-Awesome/files/1737980/snowdrift-logo_symbol_black.svg.zip).
