The main process function for processors

Parameters

bufs	bufferset of data to process in-place
start_sample	absolute timeline position in audio-samples to commence processing (latency compensated)
end_sample	absolute timeline position in audio-samples, usually start_sample +/- `nframes`
speed	transport speed. usually -1, 0, +1
nframes	number of audio samples to process
result_required	true if, on return from this method, `bufs` is required to contain valid data; if false, the method need not bother writing to bufs if it doesn't want to.
