Andrew Tridgell 9f03f5a9a9 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

Andrew Tridgell 4408eecb18 AP_NavEKF3: fixed indentation in readGpsData() 2021-07-22 16:01:00 +10:00
Andrew Tridgell cc03255245 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.
