Function libbgs::numbers::tests::test_is_generator_big

pub fn test_is_generator_big<S, const L: usize, C: SylowDecomposable<S>>(
    x: &C,
    d: (u128, usize)
)

True if x is not of order prime power dividing d, but is a prime power of d. Much cheaper than test_is_generator_small, but may return a false positive.
