Generate COLRv1 version to use this font in more situation

[CoelacanthusHex]

Firefox has supported COLRv1 since 107, Chrome supported since 98, FreeType, Harfbuzz and Pango/Cairo also supported COLRv1.
But COLRv0 is only supported by a little software. We can't use this font in GTK/Qt application.
So I hope this font can has COLRv1 version to be used more situation.

FWIW, any software that claims to support COLRv1 must also support COLRv0.. I'd be surpised if that's not the case. Twemoji currently only contains "flat" colors, no gradients, so COLRv0 is perfectly fine, and arguably more widely supported than v1.

https://caniuse.com/colr says 96.16% of browsers currently support COLRv0 while https://caniuse.com/colr-v1 says 76.6%
