Improve dynamic audio resampler filter generation
Improve dynamic audio resampler filter generation speed by 2x.
The resulting filters should be the same (excepting roundoff).
Also added check for upsampling sample rate changes to share
previously generated filters.
Modify the profiling to improve output format and sampling result
reliability.
