ANSI Colour highlighting in the editor

[Serophots]

It might be nice to add a language type to zed which will view plain text files with ANSI colour code highlighting. I suppose the terminal already implements this, it'd be nice to have it the editor too.

My use case is viewing log files emitted by tracing-appender which have colouring enabled.

Yep this is pretty rough to look at

As opposed to this from less:

Prior art, editors that already render ANSI colour escapes in a buffer:

• VS Code and forks: ANSI Colors
• Neovim: baleia.nvim
• Sublime Text: ANSIescape
• JetBrains IDEs: ANSI Highlighter Premium
• Emacs: built-in ansi-color.el

A source of such text besides logs: Ghostty's copy_to_clipboard:vt (1.3.0 notes) copies a selection with its escape sequences.
