feat: change font in text component

[dragoncoder047]

I already mentioned this on the discord but it would probably be a nice addition.

The text styles entries of the text component can have a font property that change the font, so there can be multiple fonts in the same block of text.

To minimize the texture switching the quads for all of the letters can probably just can be sorted by font, and rendered in that order, since the quads don't overlap and won't be translated by a sort.
