keyboard input has changed a lot in iced, but I think I've made the proper adjustments here. vertical splits don't seem to work, but that didn't seem to work before either. Also, there is a black border on the right and bottom of the first tab of the terminal. I'm not sure why yet, but it seems like it is probably related to the scrollbar
* Add `Metadata` struct to pass bg, underline_color, and flags info via
metadata.
* Keep and `IndexSet` of `Metadata` info in Terminal.
* Use `Metadata` info to render STRIKEOUT, UNDERCURL, and all underline
styles via `BgRect`.

* Store a font name => font faces map
* Only list font names that have `NORMAL` and `BOLD` faces with
`Normal` stretch. This will give us defaults and fall-backs that are
guaranteed to always exist.
* Filter by stretch first, with `Normal` chosen as the always existing
default.
* Then only list font weights supported by the font name stretch
selected, for the normal and bold cases.
* When changing the font name selected, the stretch/weight options
will stay the same if supported by the new font name, or revert to
the always existing fall-backs.
