relax requirements in resampler tests: use more smooth input, and 99% percentile for input & output comparisons
implement DecimationResampler (decorator for IResampler that add decimation for dynamic part of scaling factor, a.k.a. multiplier), and register "speexdec" backend that combines DecimationResampler + SpeexResampler
improve resampler tests: cleanup, cover multiple rates and profiles, add "scaling_trend" test
