Ligatures
...
This introduces a naive first pass at integrating ligatures. The basic
ligatures (such as "==" in some fonts) work great. Skin-toned emoji are
struggling a bit.
This isn't the most performant way to do this, either, and I plan on
improving that.

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.
