[BUG/PROPOSAL] SSC and CCD feature implementation

[NilsIrl]

Follow up to #1154

Features that are unimplemented:

• [ ] Preamble codes that set the row and font at the same time
• [x] Colors #1213
• [x] Allow the user to select the type of line ending they want ("\n" vs "\r\n")
• [ ] The different timing types

Closing since this has already been done and merged.

There are still parts of this that are unimplemented.

The different timing types - #1221

The different SCC timing types (dropframe and non-dropframe) are actually unrelated to #1221, which is about accounting for over-the-wire transmission time to make players like YouTube happy with the output.
