[BUG] IMX500 examples : 'tuple' object has no attribute 'x'

[camilaodsouza]

Please only report one bug per issue!

Describe the bug
Running examples imx500_classification_demo.py and imx500_object_detection_demo.py now return an error for some models.

File "/home/pi/git/picamera2/examples/imx500/imx500_classification_demo.py", line 62, in draw_classification_results
cv2.putText(m.array, "ROI", (b.x + 5, b.y + 15), cv2.FONT_HERSHEY_SIMPLEX,
^^^
AttributeError: 'tuple' object has no attribute 'x'
Aborted

This happens because imx500.get_roi_scaled now returns a tuple, so the code must be adjusted to reflect that change.

To Reproduce
imx500_classification_demo.py --model /usr/share/imx500-models/imx500_network_efficientnetv2_b0.rpk --preserve-aspect-ratio
