Added an option to disable colors from output.

[ldcvanderpoel]

ANSI colors in the output interfere with the automatic processing of results. I've added a CLI option to disable colors (--no-colors).

This required me to also make changes to how the ANSI colors are stored. They were originally directly imported from asciiarts.py, but this makes controlling these values more difficult. I've therefore added a Color dataclass and added a disable() classmethod. In order to preserve the rest of the functionality, and maintain the brevity of using single letters for colors, I've added an unpack() function that can be used to declare colors where needed locally.
