class_docstr: MJSynth Text Recognition Annotation Parser.
  
  The original annotation format of this dataset is stored in txt files,
  which is formed as the following format:
      img_path, transcription
  
  Args:
      separator (str): The separator between each element in a line. Defaults
          to ','.
      ignore (str): The text to be ignored. Defaults to '#'.
      format (str): The format of the annotation. Defaults to 'img, text'.
      encoding (str): The encoding of the annotation file. Defaults to
          'utf-8-sig'.
      nproc (int): The number of processes to parse the annotation. Defaults
          to 1.
      base_name (bool): Whether to use the basename of the image path as the
          image name. Defaults to False.
      remove_strs (List[str], Optional): Used to remove redundant strings in
          the transcription. Defaults to ['"'].
