docstr: Make a stringified representation of `self`, compatible with :meth:`EngineerStep.__eq__`
  
  Returns
  -------
  String
      String describing all critical attributes of the :class:`EngineerStep` instance. This
      value is not particularly human-friendly due to both its length and the fact that
      :attr:`EngineerStep.f` is represented by its hash
  
  Examples
  --------
  >>> def dummy_f(train_inputs, non_train_inputs):
  ...     return train_inputs, non_train_inputs
  >>> EngineerStep(dummy_f).stringify()  # doctest: +ELLIPSIS
  "EngineerStep(dummy_f, ..., ('train_inputs', 'non_train_inputs'), intra_cv, False)"
  >>> EngineerStep(dummy_f, stage="pre_cv").stringify()  # doctest: +ELLIPSIS
  "EngineerStep(dummy_f, ..., ('train_inputs', 'non_train_inputs'), pre_cv, False)"
