Write an explanation of the escape codes as text

[rgwood]

Wezterm has a wezterm replay --explain-only function which generates output like this:

        Action(CSI(Edit(EraseInLine(EraseToEndOfLine))))
        Action(Control(CarriageReturn))
        Action(Control(LineFeed))
        Action(CSI(Edit(EraseInLine(EraseToEndOfLine))))
        Action(CSI(Cursor(Position { line: OneBased { value: 18 }, col: OneBased { value: 4 } })))
        Action(CSI(Mode(SetDecPrivateMode(Code(ShowCursor)))))

It's useful to have that kind of succinct explanation in text format, Escape Artist should have a similar ability.

TODO: think real hard about the best output format, then implement it

This would be easy now that we're using Termwiz (from Wezterm) but idk, I haven't felt the need for it. Gonna close it for now, reopen if I change my mind.
