This adds support for all colors defined here, as well as their italic variants. Note that I have not tested the output because MPV doesn't appear to support SCC colors, VLC freezes while trying to open any SCC file, and I haven't been able to find any other players that support SCC. It looks fine with a visual comparison to the examples from #1120, but an actual test would be nice to have before merging.

Updated this as well, though it probably shouldn't be merged yet due to the lack of player testing.

Use youtube as a testing ground since they support SCC.

The person who requested SCC (and CCD) sent a file with colors. Either in the original implementation PR or in the issue.

#1120 (comment) (please keep in mind that the output shouldn't be exactly the same as the input files had redundant control codes)

CCExtractor CI platform finished running the test files on linux. Below is a summary of the test results:

Report Name	Tests Passed
Broken	13/13
DVB	4/7
DVR-MS	2/2
General	27/27
Hauppage	3/3
MP4	3/3
NoCC	10/10
Teletext	15/21
WTV	12/13
XDS	33/34
CEA-708	14/14
DVD	3/3
Options	82/86

It seems that not all tests were passed completely. This is an indication that the output of some files is not as expected (but might be according to you).

I'm aware of the examples, I used those to test and compare the output. The problem is that I can't find an SCC player which supports color — YouTube and MPV appear to only support white. VLC was able to display color when decoding the original EIA-608 data, but I can't get it to load any SCC files.
