Add NixOS logo
Hello!
I'd like to add NixOS logo to the repository so that users can see it in Gnome Boxes once we add our osinfo-db entries.
It's taken directly from https://github.com/NixOS/nixos-artwork/tree/master/logo and probably needs to be processed, because:
- it's not 64x64 icon,
- it has no margins, and
- the file size is huge.
Can you suggest tools to fix that?
