    A class to process texture atlases and their metadata.
    Attributes:
        atlas_path (str): The file path to the texture atlas image.
        metadata_path (str): The file path to the metadata file.
        atlas (PIL.Image.Image): The opened texture atlas image.
        sprites (list): The parsed sprite data from the metadata file.
    Methods:
        __init__(atlas_path, metadata_path):
            Initializes the AtlasProcessor with the given atlas and metadata paths.
        open_atlas_and_parse_metadata():
            Opens the texture atlas image and parses the metadata file.
            Returns:
                tuple: A tuple containing the opened atlas image and the parsed sprite data.
