docs: generates fingerprints of the input. Either provide `str` to compute fingerprint directly from your string or `fpath` to compute fingerprint from the text of the file. Make sure to have your text decoded in `utf-8` format if you pass the input string.
  
          Args:
              str (Optional(str)): string whose fingerprint is to be computed.
              fpath (Optional(str)): absolute path of the text file whose fingerprint is to be computed.
  
          Returns:
              List(int): fingerprints of the input.
  
          Raises:
              FingerprintException: If the input string do not meet the requirements of parameters provided for fingerprinting.
