Strip icon fonts to only use necessary glyphs

[otsako-vpk]

Removed every unused icon from the font files. It should also include the icon seen in https://discord.com/channels/1099468797410283540/1490107563155652839/1490107789048283417
I'd prefer if I'm given a list of glyphs instead of stripping to only what's used though. (making this a draft unless it's fine)

_{firacode font is smaller too i guess if it ever gets used

@bluepilledgreat Not sure if you get notifs from this repo, so just mentioning in case of. I'd appreciate your thoughts when you have time (mostly because this is a significant size decrease).
