_calculate_similarities crashes when tracker_dets_t is empty #56

For some frames when there are no tracks (tracker_dets_t empty), _calculate_similarities calls either _calculate_box_ious or _calculate_mask_ious assuming both contains objects

yes, this is a real problem, if you have no detections in a frame then an exception is raised when trying to calculate the similarity matrix
