A simple circular audio buffer that allows mixing multiple sources of
audio. Sources are tracked by SSRC and all sources are expected to
provide audio in the same format (same clock rate, channels, sample
format).

Only one consumer per buffer is supported, which is expected to retrieve
buffered audio at regular intervals (ptime) and so continuously empty
the buffer.

The first audio source to write into the buffer at the leading edge of
the circular buffer has its audio simply copied into the buffer, with
the leading edge advanced, while other later sources writing into the
buffer mixed into the existing buffered audio at their respective write
positions.
