+  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.
