Previously every (internal) update the decoder would advance 0 or 1 frame. Now
it will advance until it catches up. Like before, if it takes too many steps
(5) before catching up, it seeks instead. This should mostly mean seeking
forwards has less latency.

This makes the internal API more modular, but the split also forces a cleaner
implementation. It also means the OggDemuxer is now responsible for the
ogg-specific stuff like seeking and (ogg-specific) type detection.
