EKF: Fix bug in initialisation of height and magnetic field
...
This prevents zero data being used to form the initial height and magnetic field.
Do not start sampling initial values until non-zero time values are retrieved from the buffer.

This method is more suitable than a raw heading measurement because it works across a full range of pitch angles.

EKF: Add fusion method to constrain declination when unobservable
...
When fusing 3-axis magnetometer data without absolute external aiding leg GPS), the declination is ultimately unobservable and the declination of the field states and the vehicle heading will slowly drift over time. To prevent this we need to fuse in a declination to constraint the NE earth field estimates.
