Thanks for the Vorbis info!

Google added the necessary calls to its muxer, so now I'm setting SeekPreRoll and CodecDelay for Opus.

I'm also letting Opus samples remain shifted in time due to pre_skip, which the decoder should adjust for using CodecDelay.  I think this is the way I'm supposed to do it.
