Add ru_RU SNILS generator

[PetPython]

Faker version: 33.3.1

Using faker for personal data generation, I discovered that there is no method to generate russian individual insurance account number (SNILS). Thus I would like to request and develop this feature. The algorithm is pretty simple: 9 random digits + 2 digits representing a checksum.

The checksum algorithm:

def calculate_snils_checksum(value: str) -> str:
    base_snils_length = 9
    check_sum = sum(int(value[i]) * (base_snils_length - i) for i in range(base_snils_length))

    if check_sum > 101:
        check_sum = check_sum % 101

    if check_sum < 100:
        check_sum = str(check_sum).zfill(2)
    else:
        check_sum = "00"

    return check_sum

, assuming you pass 9-digits-string as a value parameter.

Is that related to SSN (faker.providers.ssn)?

If I understand correctly, no. The Russian SNILS is not directly related to the SSN, since it serves different purpose and is unique to Russia’s social insurance system.

I thought it belongs more to faker.providers.company since there are already numbers like inn and ogrn for individuals.
