[libcamera-devel] [PATCH v3 10/10] apps: cam: Add option to set stream orientation

Add a '--orientation|-o' option to the cam test application to set
an orientation to the image stream.
Supported values are the ones obtained by applying flips to the camera
sensor:
- rot180: Rotate 180 degrees
- flip: vertical flip
- mirror: horizontal flip
