Wez Furlong b35f3aa199 Add Curly, Dotted, Dashed and colored underline concept to model 
These aren't currently rendered, but the parser and model now support
recognizing expanded underline sequences:

```
CSI 24 m   -> No underline
CSI 4 m    -> Single underline
CSI 21 m   -> Double underline
CSI 60 m   -> Curly underline
CSI 61 m   -> Dotted underline
CSI 62 m   -> Dashed underline

CSI 58 ; 2 ; R ; G ; B m   -> set underline color to specified true color RGB
CSI 58 ; 5 ; I m           -> set underline color to palette index I (0-255)
CSI 59                     -> restore underline color to default
```

The Curly, Dotted and Dashed CSI codes are a wezterm assignment in the
SGR space.  This is by no means official; I just picked some numbers
that were not used based on the xterm ctrl sequences.

The color assignment codes 58 and 59 are prior art from Kitty.

README.md

wezterm-term

This crate provides the core of the virtual terminal emulator implementation used by wezterm. The home for this crate is in the wezterm repo and development is tracked at https://github.com/wez/wezterm/.

It is full featured, providing terminal escape sequence parsing, keyboard and mouse input encoding, a model for the screen cells including scrollback, sixel and iTerm2 image support, OSC 8 Hyperlinks and a wide range of terminal cell attributes.

This crate does not provide any kind of gui, nor does it directly manage a PTY; you provide a std::io::Write implementation that could connect to a PTY, and supply bytes to the model via the advance_bytes method.

The entrypoint to the crate is the Terminal struct.
