This module provides routines for dealing with ANSI colors. The two main
functions are ansifg and ansibg. With those functions, you can specify
colors in RGB and let it output the correct ANSI color escape code
according to the color depth support of the terminal (whether 16-color,
256-color, or 24bit). There are other functions to convert RGB to ANSI
in specific color depths, or reverse functions to convert from ANSI to
RGB codes.
