Error when the municipality is old (active = false) and the person is more than 100 years old

Example:

codicefiscale.encode('Michele', 'Faedi', 'm', '01/01/1907', 'Gallico')

I also have a solution. I try to create birthdate_str until it work or at maximum 3 attempt. Each attempt decrease the birthdate_year by 100.

def decode(code: str) -> dict[str, Any]:
    """
    Decodes the italian fiscal code.

    :param code: The code
    :type code: string

    :returns: The data associated to the code and some additional info.
    :rtype: dict
    """
    raw = decode_raw(code)

    code = raw["code"]

    birthdate_year = int(raw["birthdate_year"].translate(_OMOCODIA_DECODE_TRANS))
    birthdate_month = _MONTHS.index(raw["birthdate_month"]) + 1
    birthdate_day = int(raw["birthdate_day"].translate(_OMOCODIA_DECODE_TRANS))

    if birthdate_day > 40:
        birthdate_day -= 40
        gender = "F"
    else:
        gender = "M"

    current_year = datetime.now().year
    current_year_century_prefix = str(current_year)[0:-2]
