encode text color and style with a two ascii characters.
asciicolor is a protocol which encodes text color in terminals and (in future) elsewhere using only a single ascii character: i.e. b for black, w for white and n for navy blue, etc. Capitalizing the character encodes a style (bold for foreground, underlined for background).
See #asciicolor.Color for all codes.
The color codes are used by #asciicolor.style.Styler to style text using an AcWriter. See #vt100.AcWriter for the reference spec.
