Add full yolov8 compatible post-processing (#115)

This updates the local detection to yolov8-based models from the older yolov5 based models.

This includes significant additional post-processing of the raw yolov8 output, but also means that the smaller nano yolo model is available as well as all of the updated ALVINN thorax training data.
