Paul Riseborough 03f3df7415 EKF: Fix bug in output observer 
Bug was causing output observer state history to be stored at the the EKF, not IMU output rate and resulted in degraded tracking performance

find_package(Eigen3).

When transitioning into optical flow nav  from a non-aiding condition during ground operation, ensure position covariances are reset as they could be invalid.

This ensures a consistent correction is applied after every covariance prediction or correction.

Paul Riseborough f1b7e7714e EKF: Make average update rate of EKF closer to target 
With the EKF, the average update rate is more important than the instantaneous value as it affects tuning. This patch ensures that the EKF prediction cycle will be performed early if the previous one was late in an attempt to maintain the target update rate.
