MainCode/adalm1000_logger.py aktualisiert

Thread Management:

        Changed MeasurementThread to inherit from QThread instead of QObject

        Added proper thread cleanup in reconnect_device()

        Added checks for thread existence before attempting operations

    Error Handling:

        Added more robust error handling around thread operations

        Ensured proper cleanup of resources during reconnection attempts

        Added checks for thread running state before attempting to stop it

    Initialization:

        Explicitly initialized thread variables to None

        Added proper null checks before accessing thread methods

    Device Reconnection:

        Improved the reconnection flow with better cleanup

        Added status messages to keep user informed
