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/)
Additional context
The reason why this is not a feature currently is that the panel AREPL displays is HTML, not a console (aka terminal aka command prompt) that displays colored text.
