Switch to using emojis for emotion system (and animations)

[kasumi-1]

There has been persistent problems with having the chatbot use the correct format of [emotion] message. An idea shared with me was to instead utilize emojis. These fail gracefully, and there should already be a lot of training data utilizing emojis. We can search for specific types, and trigger expression changes, or for some emojis - trigger animations. This should hopefully allow a non-finetuned model to be able to trigger any of the gestures and expressions already exposed by the emoji system, will need to import the animations to make this fully work.

A much larger amount of expressions can be grabbed correctly (see https://emojipedia.org/smileys )

Some I think interesting from https://emojipedia.org/people :

• thumbs up/down
• waving
• dancing
• bowing
• facepalming
• juggling
• lotus position

This is a pretty large change but I think it should provide a much better route.

We also should save some space in prompt context.
