Daniel Agar 1b5e65df04 gyro_fft: change default length 1024 -> 512 to decrease latency ...

- change default FFT length (1024 -> 512)
      - this doubles the update rate because half the number of samples are required for each
 - decrease number of peaks (4 -> 3)
      - so far 3 seems to be sufficient on most vehicles
 - increase median filter window (3 -> 5)
 - decrease SNR requirement (likely needs to be configurable)
