    Loads YOLO annotations and returns class names, images,
        and their corresponding detections.

    Args:
        images_directory_path (str): The path to the directory containing the images.
        annotations_directory_path (str): The path to the directory
            containing the YOLO annotation files.
        data_yaml_path (str): The path to the data
            YAML file containing class information.
        force_masks (bool, optional): If True, forces masks to be loaded
            for all annotations, regardless of whether they are present.

    Returns:
        Tuple[List[str], Dict[str, np.ndarray], Dict[str, Detections]]:
            A tuple containing a list of class names, a dictionary with
            image names as keys and images as values, and a dictionary
            with image names as keys and corresponding Detections instances as values.
