Generate QuickDraw bitmap examples.

    Given a list of file paths with data for each class label, generate examples
    in a random order.

    Args:
      file_paths: (dict of {str: str}) the paths to files containing the data,
                  indexed by label.

    Yields:
      The QuickDraw examples, as defined in the dataset info features.
