Paul Riseborough 9f3b1351f7 EKF: Don't initialise velocity to GPS on initial alignment 
For initial alignment the velocity and position should start at zero

Paul Riseborough 7677a162aa EKF: Don't start the output observer before the main filter has initialised 
This prevents the possibility of output transients if alignment is delayed.

Paul Riseborough a711632017 EKF: Add method to fuse horizontal magnetometer data 
This method is more suitable than a raw heading measurement because it works across a full range of pitch angles.
It has been made the default for ground operation.

Paul Riseborough 9d7340e187 EKF: Fix bugs in position and velocity resets 
The position reset was not being compensated for velocity and measurement delay
The height was being reset with the position. It has been moved into a separate reset function
The maximum accepted GPS delay of 100msec was inadequate
The states  was being incorrectly reset to the GPS position and Baro height on initial alignment.

Paul Riseborough dbb8e12948 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.

Roman 0b5c90574c fix delta angle bias usage: 
the delta angle bias was applied to imu data which was not coming in the same
time intervall as the filter was operating. Therefore, the delta angle bias
applied to new imu data had to be scaled correctly in order to match
the imu time interval.
