Called on the audio stream thread when a PCM packet is received for the
stream. |data| is an array representing the raw PCM data as a floating
point type, i.e. 4-byte value(s). |frames| is the number of frames in the
PCM packet. |pts| is the presentation timestamp (in milliseconds since the
Unix Epoch) and represents the time at which the decompressed packet
should be presented to the user. Based on |frames| and the
|channel_layout| value passed to OnAudioStreamStarted you can calculate
the size of the |data| array in bytes.
