Support Embedded Cue files

From @robUx4:

"Right now we support AUDIO and BINARY (mixed binary+audio in a ".bin" file) modes. The WAVE mode uses an audio file that can be all kinds of format (.wav, .mp3, .flac, .tta, etc).

It's currently possible to handle WAVE sources, but seeking in them is inaccurate (because they are not raw PCM). The underlying reading of audio blocks might need a proper internal demuxer, capping the start/end PTS in the underlying file to match the tracks in the .cue file."

Ogg and WV files mostly.

Will upload files later.
