font: introduce Group which will eventually replace FallbackSet
...
This is more oriented around glyph indexes and also introduces an
important concept in the FontIndex which can be cached ahead of time so
that we can eventually break down text into runs for text shaping.

Charsets
...
Initial charset support. This gets a lot of stuff working but still has some critical (but not very real world) limitations.
Implements:
* All charset slots G0 to G3
* All shifting commands to shift into GL and GR
* Single shift commands `ESC N` and `ESC O`
* UTF8, ASCII, British, and DEC Special Graphics character sets
Notably missing:
* A number of rarely used charsets
* NRC handling
* Disabling UTF-8 mode
All the missing stuff is very edge case... but necessary for correctness.
