Merge branch 'chiyu'

- Added handling for SYS_STATUS and STATUSTEXT messages in mainOrchestrator.py and mavlinkObject.py.
- Introduced a new StatusTextEntry data class in mavlinkVehicleView.py to manage status text messages.
- Updated topic management in mavlinkROS2Nodes.py to include new status text functionality.
