Not only is this tag optional in Interop and SMPTE, but it would appear that if it is present but empty a DCP will not play back on Sony SRX320 / LMT3000 systems (DoM bug #2124). Here we use optional<>, as seems to make sense, and also refuse to write empty tags (instead omitting the tag entirely).

Fix off-by-one in verification of closed caption line length.
