some question about #49 and #85

[ysys98]

https://github.com/AlexeyAB/darknet/issues/49 https://github.com/AlexeyAB/darknet/issues/85 I refer to the above steps to modify the code and recompile it, and after rostopic echo /darknet_ros/bounding_ boxes, the ID of each detected object will be displayed, but when the camera captures two identical objects, their IDs are the same. For example, the ID of person is 0, the ID of apple is 57, and the ID of both apples is 57. How can we distinguish them by setting different IDs in the same category of objects like https://github.com/AlexeyAB/darknet/issues/49?
