- log all estimator (ekf2) flags as separate booleans in a new dedicated low rate message (only publishes at 1 Hz or immediately on any change)
- this is a bit verbose, but it avoids the duplicate bit definitions we currently have across PX4 msgs, ecl analysis script, flight review, and many other custom tools and it's much easier for casual log review in FlightPlot, PlotJuggler, csv, etc
- for compatibility I've left estimator_status filter_fault_flags, innovation_check_flags, and solution_status_flags in place, but they can gradually be removed as tooling is updated

The MAVLink specs for CreateFile in MAVLink FTP were updated on Dec 23, 2020 (today) with a behavior change to truncate a file if it already existed, following the UNIX standard behavior: https://pubs.opengroup.org/onlinepubs/9699919799/functions/creat.html. This change is tracking that spec change. While it is a functional change, the limited usage of the FTP protocol and the fact that implementations should not rely on error states to determine wether to truncate a file or not makes this a viable change.
Without range finder, the validity flag goes to false quite quickly and
if can be that a vehicle never starts HTE is the takeoff is too slow.
In this specific context of takeoff detection, since
the exact value is not important, we can safely ignore the validity flag.
the _landed flag only is not enough to tell if the drone is still touching
the ground, so an additional check based on the altitude AGL is required.
to have this in_air detection correctly updated, the module needs to be
scheduled on the vehicle_local_position message as no setpoint is
produced in non-assisted modes.
