  + * @brief The MissionRaw class enables direct access to MAVLink mission items.
  + *
  + * This plugin gives direct access to the MAVLink mission protocol which
  + * means full control over waypoints and waypoint actions/commands. However,
  + * this means that not all functionality provided is actually implemented or
  + * correctly supported by a flight controller.
  + *
  + * For a tested, simpler subset in mission functionality, it is recommended
  + * to use the `Mission` plugin.
  + *
  + * @note Currently, only downloading the mission items is implemented,
  + * uploading could be added in the future if required.
