ANSI colors for Python

The `ansicolors` library provides a simple way to add ANSI escape codes for foreground, background, and text styles to strings for terminal output. It supports 8-color, 256-color (xterm), and 24-bit RGB color definitions. The current version is 1.1.8, released in June 2017, and the project appears to be in maintenance mode due to lack of recent updates.
