Convert an arbitrary String of text into a sequence of actions.

If the input string ends with a partial ANSI escape sequence, it will be yielded as a Remainder action, which should then be prepended to the next call to parse.

The events relevant to interpreting the stream.

• SetForeground corresponds to \e[3Xm and \e[4Xm where X is the color
• SetBackground corresponds to \e[9Xm and \e[10Xm where X is the color
• SetBold corresponds to \e[1m
• SetFaint corresponds to \e[2m
• SetItalic corresponds to \e[3m
• SetUnderline corresponds to \e[4m
• SetInverted corresponds to \e[7m
• Linebreak corresponds to a \n character
• CarriageReturn corresponds to a \r character
• Print is a chunk of text which should be interpreted with the style implied by the preceding actions (i.e. [Bold True, Print "foo"]) should yield a bold foo
• Remainder is a partial ANSI escape sequence, returned at the end of the actions if it was cut off. The next string passed to parse should have this prepended to it.

The colors applied to the foreground/background.
