Add support for webvtt in MP4 segments output.

Closes #272

I think I addressed all the feedback except for the named constants in ParsePacket26 that might require having to carefully go through the spec to come up with some meaningful names for.

I propose we merge this as is (on account of it works and has tests) and then can improve it in the future (such as when adding support for other languages).
