Fixed performance issue with IIR filter
...
Passing samples with zero value (0.0) causes very slow processing of
IIR filter on my test machine 'nuedel'. I don't know why.
To solve this, I add a very small number to each input sample.

Make run faster on ARM CPUs using fast math approximation
...
Use --fast-math to use sine/cosine tables and approximate atan2.

FM modulation: Never turn carrier completely off
...
This prevents IIR filter to become very slow for some unknown reason.
