PetrovichGenderDetector raises StopIteration instead return ANDROGYNOUS gender

[kosdmit]

Код ниже вызывает исключение StopIteration:

gender_detector = PetrovichGenderDetector()
gender = gender_detector.detect(middlename='Блаблабла')

Думаю в таком случае метод detect должен возвращать Gender.ANDROGYNOUS

Pytrovich merely clones the original Petrovich behavior, will check whether it returns the same response.

For example, we need to always use try-except with PetrovichGenderDetector:

        gender_detector = PetrovichGenderDetector()
        try:
            gender = gender_detector.detect(lastname=lastname, firstname=firstname, middlename=middlename)
        except StopIteration as e:
            logger.warning(f'Can not to predict gender to inflect {self.signatory}, default value will be used (MALE)')
            gender = Gender.MALE

It's not intuitive, especially the StopIteration exception.
Probably it would be better if we would returned ANDROGYNOUS or something like UNKNOWN. What do you think?
