escape_code_length: test all setaf parameters

Browse source 
Taking a different approach here. I can't see why we'd only want to
recognize certain colors. Now, we'll just try all the colors fish might
use.

This could probably be optimized now that there are more
than 8 (or 16) colors fish can do.
