Double load of matching image in realtime.py

[AndreaLanfranchi]

Consider this snippet

                                # to use this source image as is
                                display_img = cv2.imread(label)
                                # to use extracted face
                                source_objs = DeepFace.extract_faces(
                                    img_path=label,
                                    target_size=(pivot_img_size, pivot_img_size),
                                    detector_backend=detector_backend,
                                    enforce_detection=False,
                                    align=False,
                                )

display_img is firstly initialized by a direct load of image from file on disk
Eventually DeepFace.extract_faces is called passing the string path to file (which implies a second load)
IMO the code should like

                                # to use this source image as is
                                display_img = cv2.imread(label)
                                # to use extracted face
                                source_objs = DeepFace.extract_faces(
                                    img_path=display_img,
                                    target_size=(pivot_img_size, pivot_img_size),
                                    detector_backend=detector_backend,
                                    enforce_detection=False,
                                    align=False,
                                )

Right, second usage will avoid re-load twice.
