/**
* RawDiskStream. This can stream raw PCM audio data from disk. The
* function takes an pointer to an array of RawDiskStreamAudioBlock which defines the
* start position and length of each block of uncompressed audio in the stream.
* This is a stream, which allows for playing raw PCM data from a stream.
* It also features playback of multiple blocks from a given stream.
