Minimum requirement to use: set IMU_GYRO_RATEMAX to 400.
Logging rate of a single topic: ~85 KB/s. If multiple should be logged,
a really good SD card has to be used.
- do not gps reference altitude to zero in case gps checks pass before the
filter initialized
- reset the filtered gps position and position derivative filters in case
we are in air or there is movement on the ground

Greatly improves the noise on the d-term on a Kopis 2. Apparently the order
of filtering vs differentiating matters.
Also disables the DGYRO filter by default, as the D-term now already has
a default filter of 30Hz applied.
It cause bad transfers on a Kopis 2, though not on a bench KakuteF7 unit.
Not sure if this is a single case.
