Enum DynamicDispatchNTT

pub enum DynamicDispatchNTT<F: BinaryField> {
    SingleThreaded(SingleThreadedNTT<F>),
    SingleThreadedPrecompute(SingleThreadedNTT<F, PrecomputedTwiddleAccess<F>>),
    MultiThreaded(MultithreadedNTT<F>),
    MultiThreadedPrecompute(MultithreadedNTT<F, PrecomputedTwiddleAccess<F>>),
}

An enum that can be used to switch between different NTT implementations without passing AdditiveNTT as a type parameter.
