Sample block merging code should not be duplicated across the DSPs that
require it, but instead should be a common function. Also added some
optimizations to the Float32 converter function, to bypass conversion if
the audio format needs no conversion.

Audio Chunks now have full timestamp accounting, including DSP playback
speed ratio for the one DSP that can change play ratio, Rubber Band.
Inputs which support looping and actually reporting the absolute play
position now do so.

FreeSurround, like the Equalizer, which attempt to coalesce Audio Chunks
into larger blocks of 4096 samples, must check if the audio format has
changed between blocks, and stop stacking chunks together when a new
format is detected. They will continue processing with less sample data
than expected, as necessary.
