Add ANSI terminal "mocking"

[joachimschmidt557]

I think it would be nice to include a terminal emulator (basically an interpreter for ANSI escape sequences) in this repository as well. Something along the lines of https://github.com/selectel/pyte for example.

This would enable testing zig libraries and applications which use ANSI escape sequences for correct display without requiring a "real" terminal emulator like xterm and manually checking the output. Maybe this can even help in developing "real" full-featured terminal emulators.

alacritty/vte and wezterm/vtparse based on A parser for DEC’s ANSI-compatible video terminals
Here is C-implementation: vtparse

@data-man Thanks for the material! I'll have a look at them before I can implement such a feature.

But maybe a full-featured VTE parser should belong into a new repository. Hmm
