EKF: Fix scaling error in covariance prediction derivation
...
The covariance prediction derivation was using the noise 1-std value instead of the noise variance. This resulted in the values of IMU process noise required to tune not matching the observed covariance growth.

EKF derivations: Correct error in direct yaw and declination angle fusion
...
The atan function is now being used correctly instead of the tan function. This fixes problems with large heading errors or declination values.
The simple heading fusion has been decoupled from the magnetic field measurements. This enables external yaw measurements to be used in the future.
