Please add a license

[hoxxep]

Hello,

Great icons! It's unclear what license these icons are under from the Github repo, and the default would be to assume a restrictive license. Would it be possible to include a license file we can link to, as Iconify suggests they're CC 4.0.

Thank you!

Cheers,
Liam

This. Upvoting for a CC0 license in my case.

I'm aware of an open-source project that is interested in these icons but there is no declared license. Please add an explicit license declaration here on github.
