Function discrete_logarithm::discrete_log_with_factors

pub fn discrete_log_with_factors(
    n: &Integer,
    a: &Integer,
    b: &Integer,
    n_factors: &HashMap<Integer, usize>
) -> Result<Integer, Error>

Compute the discrete logarithm of a in base b modulo n (smallest non-negative integer x where b**x = a (mod n)).

If the prime factorization of n is known, it can be passed as n_factors to speed up the computation.
