Apply Color SVG transform with svgo

[13rac1]

The required color SVG transforms are currently applied as a "SVG transform" I'd prefer them "baked" into the actual SVG data to reduce potential hassles and file sizes. svgo can do this.

Re-open if there is an important benefit to this. Minor file size reductions aren't worth it IMO right now.

Now labeled as a bug since it may cause some issues with Windows.

Tests show it doesn't cause a bug, but is still recommended.

Using svgo via STDIN/STDOUT should work:

svgo --enable=convertTransform -i - -o - < emoji.svg
