move OS-related #defines to .h file; speed improvements
Combine two loops in stereo CIC computation into one for-loop.
Add compiler optimization "unroll-loops" to isr if OS enabled. Speed
improved from 113µs to 65µs per isr call for CIC interpolation filtering
(Measured on Teensy 3.2 96MHz optimized).
