/** @brief Implementation of gyro attentuated low pass filter
*
* Uses the magnitude of the gyro signal to guide a simple low-pass filter.
* Faster gyro motion allows the filter to be more responsive, slower
* motion smooths the signal. The intended behavior is that when the
* user is moving slowly, the response is smoother. While this introduces
* latency, its not as noticeable at slow speeds, where smoothness and
* stability are more important. During fast motions, the gyro magnitude
* is high, which allows the filter to pass the signal through "raw" so
* there is no latency or smooth. Fast motions tend to be imprecise,
* so low latency is more important than smoothness. Slow motions are
* assumed to be "precision" adjustments, which can have some latency
* at the cost of smoothing.
*
* @note
* I think this filter feels best for twitchy precise motions. If the
* user does a lot of fine corrections, or a lot of "medium speed" motions
* it will feel sluggish. But for a precise user, it acts fast when
* twitching and then stabilizes on the local area.
