Force Landing

Not supported by the current firmware.

After calling, the aircraft will land directly to the ground regardless of whether there are obstacles. Use the drone_emergency_stop command to cancel. After landing, the aircraft can only be retrieved manually. Use with caution! (seq is an incrementing sequence number to ensure commands are executed in order, at the same level as data)
