Subject: Allow more than one peaks_ready callback to be pending for an
 AudioRegionView at any one time.  Prevents problems when there is more than 1
 channel for which peaks are not ready; before, the first peaks_ready callback
 would be forgotten when the second one was requested.  Should fix #3074.
