Support styled and colored underlines about anotherterm HOT 3 OPEN

It is from the kitty's Terminal protocol extensions.
Why not to add? It will be done.

At the moment, you can also try this trick though:

echo -e '\e[97mX\e[1;31m\xE1\xAA\xB6\e[0m'

It uses the ability to set separate colors of the combining glyphs. (Another Term only, it seems...)
The combining glyph here is U+1AB6.

I'm not sure whether AnotherTerm already supports custom fonts, Termux does, and I rely on it for having Nerd Fonts with Powerline glyphs. Sadly Termux doesn't support specific fonts for italic, etc, I can only set one regular font and bold/italic is done automatically, from what I can tell from AnotherTerm's codebase, it seems it's possible to set custom fonts, specific for bold and italic, besides the regular one?

Eager to try your impl when it's done.
