New nodes to handle/visualize bboxes

This Reddit post from r/StableDiffusion introduces new custom nodes for ComfyUI designed to handle and visualize bounding boxes (bboxes) in image workflows. The BboxVisualize node highlights specified bounding boxes directly onto images, making it useful for visually inspecting object locations — an essential tool for image processing tasks involving object detection and localization. Use cases include enhancing visualization of detected object boundaries to validate localization accuracy, as well as visually debugging object detection models by highlighting true and false positives.
