Function: ansi-color-apply-sequence

Apply ESCAPE-SEQ to CODES and return the new list of codes.

ESCAPE-SEQ is an escape sequence parsed by `ansi-color-parse-sequence'.

For each new code, the following happens: if it is 1-7, add it to
the list of codes; if it is 21-25 or 27, delete appropriate
parameters from the list of codes; if it is 30-37 resp. 39, the
foreground color code is replaced or added resp. deleted; if it
is 40-47 resp. 49, the background color code is replaced or added
resp. deleted; any other code is discarded together with the old
codes. Finally, the so changed list of codes is returned.
