Enhance Simba with the power of the rainbow🌈

[Torwent]

Gives full BGR output color support to Simba output (and editor I think).

I'm not sure if you would like this in Simba or not but I think it's kinda nice to have things more flexible and also extensible as I made it somewhat easy to add a few more flags in the future if we want. Speed wise, should be roughly the same as before except special strings have one extra byte.

This is also likely my biggest Simba change ever so I would appreciate it if do a good review of my changes in case I missed anything and of course, you are free to change and improve anything you don't like about it.

Here is a video preview of what this does:

One thing I was also considering was controling the "Alpha" which you have hard coded but I kinda like this tinted look.

Anyway if this is merged, I would also like to also try and give per character color inside of each line someday.
But that would be something for another day and it would be quite a different proposal as that requires iterating over the string.

My idea would be to add a TEXT_COLOR flag to know we have character colors enconded in the string and if we have that flag we iterate the string looking for #0#0'BBGGRR' and color the next characters.
But yeah, something for another day!

  STR: String = 'Hello world!';
begin
  WriteLn #0#0#4 + '00A0FF' + STR;
end.
