New nodes:

• Classify images using ONNX-models (tested for timm library with support for more than 1k different models)

Node updates:

• Draw Boxes: draw with class idx and score
• Object detection / ONNX Load: determine model input sizes automatically from ONNX session

Future work:

• further tune for exact reproduction of classifier outputs python vs. onnx, currently near-prefect reproduction on 2nd digit
