Mode::get_pilot_desired_heading_and_speed() directly takes the steering and throttle input from the RC object instead of using Mode::get_pilot_input(). This means simple mode will not work correctly with two paddle input.

This should be quite a straightforward fix it just needs to be tested afterwards to be sure the fix is correct.

There seems to be some issues with the landing function in ./software/px4_mavros_scripts/1_px4_mavros_offboard_controller/commander.py.

To do:

1. Test the land function and report if it works well.
2. Fix if there is an issue.
