Mathias Agopian 0bcd713977 fix [3369027] Sensor.TYPE_ROTATION_VECTOR is unstable and returns NaNs when running slowly
The cut-off frequency of the lowpass filter was too high
for the sampling rate used by DELAY_NORMAL.

Now we use the same filters used for the gravity vector
(cascaded biquad at 1.5 Hz)
