Download OpenMoji releases directly? Download .tar.gz rather than .tar

[SamHasler]

Is it possible to configure emojify to download the OpenMoji releases directly,
i.e. download a .tar.gz from the assets listed here:
https://github.com/hfg-gmuend/openmoji/releases

rather than a .tar from the files in this repo:
https://github.com/iqbalansari/emacs-emojify/tree/images

I can see the above files listed in the data/emoji-sets.json file, which I could presumably edit, but I assume it wouldn't know what to do with a .tar.gz file as it's expecting a .tar.
