yolo26obbtensordec

Tensor decoder element for Yolo oriented bounding box detection. This supports YoloV10-obb, Yolo11-obb, Yolo12-obb and Yolo26-obb but only the one-to-one (end2end, NMS) heads.

This takes webcam input, performs oriented object bounding box detection via onnxinference on it, decodes the inferred tensors with yolo26obbtensordec and then overlays the detected objects on the frame via objectdetectionoverlay.
