save significant IMU bias changes learned by the EKF
* ekf2: make publishing of learned accel biases more robust
* ekf2: reset accel bias if calibration updated
* msg: add separate accel and gyro calibration counters
* ekf2: use separate accel and gyro calibration counters
* ekf2: rework logic to reset biases when calibration counters increment
* sensors: add saving of learned accel biases
* ekf2: generalized saving accel/gyro/mag in flight sensor calibration
* boards: holybro kakutef7 disable systemcmds/perf and systemcmds/top to save flash

Daniel Agar 48f125f150 estimated IMU bias preflight checks
- commander preflightcheck use estimator_sensor_bias message instead of EKF state index magic number
 - ekf2 publish estimated bias limits in estimator_sensor_bias
 - preflightcheck only error if bias estimate exceeds half of configured limit (delete COM_ARM_EKF_AB and COM_ARM_EKF_GB parameters)

save learned mag bias per sensor (Multi-EKF support)
- handle saving the mag bias per sensor (across all estimator instances using that mag) in sensors/vehicle_magnetometer
 - this is now saving back to the actual mag calibration CAL_MAGn_OFF{X,Y,Z}
 - ekf2 reset mag mag bias on any magnetometer or calibration change
 - use Kalman filter scheme to update stored mag bias parameters using all available bias estimates for that sensor

Daniel Agar e5879f1bb6 estimator_sensor_bias: add bias variance 2020-09-04 10:48:26 -04:00
Daniel Agar 20c2fe6d28 estimator messages add explicit timestamp_sample
- timestamp is uORB publication metadata
 - this allows us to see what the system saw at publication time plus the latency in estimation
