Replacing emoji descriptions with their emojis

Going from :tada: to 🎉 and things like that.

While we're talking about emojis, since some terminals/fonts don't properly support them, going the other way around would be nice too

https://github.com/kyokomi/generateEmojiCodeMap might be useful, it can create a text -> emoji mapping like this. Alternatively, the data in https://github.com/github/gemoji can be used directly

the text mapping looks like it should get the job done

It would (for performance) probably be best to try to find the relevant parts in the messages with a regex and then map them to their emoji counterparts using that map. Having an inverse map for displaying the text representations shouldn't be too hard. Thanks for doing the quick research on it!

I am looking into this issue currently.

Can we use kyokomi/emoji directly inside gomuks? I believe that would make this issue very easy.

The Sprint function of that library can be used directly, but a new function is probably needed for the emoji->text conversion (for terminals/fonts that don't support emoji properly).
