🤖 Generated by Copilot at 73fe8a9

This pull request adds a feature to show the IoU score for each image ROI on the image for debugging the image projection based fusion algorithm. It modifies the fuseOnSingleImage function in node.cpp to pass the IoU data to the Debugger class, and adds a new variable max_iou_for_image_rois_ to debugger.hpp. It also updates the publishImage function in debugger.cpp to draw the IoU score on the image.
