[libcamera-devel] [PATCH v9 7/7] qcam: Add --script to load capture script

[Utkarsh Tiwari]

Add --script as an individual option to load capture scripts.
Load the capture script before starting the capture.

If an invalid capture script has been given, display an critical error
QMessageBox and close the application.

 Differences from v8:
    1. Functionally the patch remains same.
    2. The difference is that checking for OptCaptureScript is now done
    in MainWindow::MainWindow()
