/*
Emoji merger script, quick hack of a tool to:
- update some missing emoji from an external source
- sort the emoji
- remove all multipart emoji (reactions don't allow them)
Merges emoji from here: https://gist.github.com/oliveratgithub/0bf11a9aff0d6da7b46f1490f86a71eb
to the simpler format we're using.
