feat: caption services metadata support #131

Closed gkatsev closed 3 years ago

Parse out Accessibility elements to see 608 and 708 signaling as defined in ANSI_SCTE 214-1 2016. These translate to the same CC object that m3u8-parser outputs with instreamId matching. Using https://livesim.dashif.org/livesim/testpic_2s/cea608_and_segs.mpd and this module linked in, I can see that the labels are showing up.

TODO:

[x] 608 parsing
[x] ~708 parsing~
[x] tests, lots of tests.

Looks like signaling default in the manifest is coming as part of the next iteration of ANSI 214
