Should we process flags?

Flags, as unicode composites, are getting quite popular on Twitter, and might be useful to recognise as national or linguistic entities.

A very simple start on this could be to add a gazetteer of the standard flag unicode sequences mapped to their ISO codes.

Turns out flags are actually a lot more complex than I thought: https://blog.emojipedia.org/emoji-flags-explained/

Should be easy enough to cover the basic cases either with a gazetteer or with some JAPE to find all valid combinations so we can mark them as a flag even if we can't determine what it represents.
