Handle ansi control codes for colour

Console within VSC on Windows shows those:
grey = "\x1b[38;20m"
yellow = "\x1b[33;20m"
red = "\x1b[31;20m"
bold_red = "\x1b[31;1m"
reset = "\x1b[0m

This should work without installing the colour-theme for windows.

I could just install the colour-theme for windows, but did not try yet. (https://www.howtogeek.com/322432/how-to-customize-your-command-prompts-color-scheme-with-microsofts-colortool/)
