EKF: Don't make detection of indoor operation dependent on optical flow
...
This is required because it can take several seconds for an optical flow sensor operation to be confirmed and there are also many use cases for indoor operation where no optical flow is used.

EKF: Reset yaw gyro bias learning when resuming use of magnetometer
...
The previous lack of yaw drift constraint will also mean that the yaw gyro bias estimate is likely to be incorrect and needs to be re-learned.

EKF: Don't start using mag if optical flow use is interrupted
...
If magnetometer use is being inhibited because an indoor condition has been detected (optical flow and poor or no GPS) and the optical flow fusion checks fail causing the EKF to stop navigating, we do not want the EKF to start using the magnetometer.
