Quaternion: go back to the full update_MARG()
...
the separate drift controller is too erratic on yaw hold to be usable
at the moment

we get linear accelerations of more than 1g when turning corners

Quaternion: fix the gyro bias in centripetal and remove smoothing
...
the centripetal code needs to take account of the current gyro
bias.
It turned out that the accel and gyro smoothing was causing
significant control lag, and we're better off just letting the
quaternion code handle it via its own smoothing parameters

Quaternion: use GPS to correct for linear acceleration
...
this gives much better pitch estimates. We should do this with the
airspeed sensor if available.

this is for experimenting with the Madgwick quaternion system, to see
if it is more or less noise sensitive than DCM
