* Change WaveFileModel API from getValues(start,end) to getData(start,count).
It's much less error-prone to pass in frame counts instead of start/end
locations. Should have done this ages ago. This closes #1794563.
* Add option to apply a transform to only the selection region, instead of
the whole audio.
* (to make the above work properly) Add start frame offset to wave models
