tsparse: Implement timestamp/retimestamping of output buffers
When the set-timestamps property is set, use PCRs on the provided (or autodetected) pcr-pid to apply (or replace) timestamps on the output buffers, using piece-wise linear interpolation. This allows tsparse to be used to stream an arbitrary mpeg-ts file, or to smooth jittery reception timestamps from a network stream. The reported latency is increased to match the smoothing latency if necessary.
