The contact_thresh_N, contact_thresh_pos_N and contact_thresh_neg_N argument is deprecated by removing the suffix '_N' with all the move_to(),move_by(), translate_by() and rotate_by() APIs that is associated with stepper motors after the new contatc models feature introduced to the stretch_body.

This adds show_debug_images at the node level. When set to True,
debugging images are displayed via OpenCV, including RGB images
annotated with ArUco marker detections, marker masks, and depth
images used when estimating the pose of the ArUco markers.
