Description

This patch adds VERBOSE parsing of some XDS data. I was using this code to see if the V-Chip information chagned during commercials as a possible detection method, but it doesn't appear to be the case, at least with my XDS data. I'd be interested to see what others find using this. There is also a Program Type code that is parsed and has a possible value of Advertisement but this might be for late night paid programming vs. a commercial during a program.

Much of the information was gathered from http://www.geocities.com/mcpoodle43/SCC_TOOLS/DOCS/CC_XDS.HTML and http://captioning.robson.org/articles/general/nv-line21.html

(In [8946]) Closes #862, by applying patch from Kevin Kuphal.

This adds XDS parsing to CCDecoder. XDS contains information about the currently playing program during NTSC and some ATSC programs. We do not currently use the information, but if you run with '-v VBI' you can see all the information available.
