Daniel Agar 833cdc9236 EKF2 update GPS and airspeed delay defaults (#7353)
* update ecl to latest

* EKF2_GPS_DELAY change default 200ms -> 110ms

 - 110msec is more representative of what most users are flying

* EKF2_ASP_DELAY change default 200ms -> 100ms

The EKF is relatively insensitive to airspeed sensor delays and the effective delay is installation specific, so it has been set to a value that does not cause the data buffers to be longer than is required to accomodate GPS delays.

Paul Riseborough 889fb30029 ekf2: Improve control of magnetometer bias learning
Adds parameters so that the motion checks used to switch between magnetic yaw and 3-axis fusion can be adjusted.
Modifies the check used to determine if learned mag biases  can be saved. A cumulated calibration time is used rather than continuous calibration time to allow for for switching in and out of 3-axis fusion mode that is required to do calibration.

Beat Küng eaa9e6a019 ekf2: set att.timestamp to now in replay mode before ekf is initialized
logger will always log this topic, and a 0 timestamp will look worse in
FlightPlot. This will show a period of 0 attitude instead before ekf
is initialized.

Beat Küng 2220c3a60d ekf2: use sensors timestamp for published topics when in replay mode

thus we just use the same timestamp as the input sensors.

Paul Riseborough 699edd2535 ekf2: Prevent loss of baro data due to buffer time arrival checks
Baro data arriving too soon after the last measurement due to a high sampling rate or timing jitter is rejected inside the ecl EKF to prevent the data buffer overflowing.
This patch checks the timestamp difference from the last measurement, and if to small, the data is accumulated and the average sent to the EKF when the time delta
is acceptable.

Paul Riseborough ef7ed97cbd ekf2: Don't send un-usable mag and baro data to the EKF
Fixes:

1) Invalid data with a zero time stamp could be the EKF ends up in the data buffers and result in loss of 'good' data from the buffers

2) Magnetometer data was arriving at a rate faster than the data buffers could handle resulting in loss of data.
