AP_NavEKF3: process GPS yaw independently of GPS fix
...
this processes GPS yaw with its own timestamp and as a separated step
from fusing position and velocity. This makes the yaw time handling
more accurate as yaw for moving baseline GPS comes in as a separate
piece of data from the position and velocity

AP_NavEKF3: implement moving origin
...
this shifts EKF_origin to the current location at 1Hz, while leaving
public_origin alone. All output APIs and logging are relative to
public_origin.
The effect of this change is to remove the distortion caused by a
spherical earth, which allows the EKF to operate without errors at
very long distances from the public_origin.
