[libcamera-devel] [PATCH v4 3/3] 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, show error
but start the capture without the script.
