pub fn sum_primitive<T>(array: &PrimitiveArray<T>) -> Option<T> where
    T: NativeType + Simd + Add<T, Output = T> + Sum<T>,
    <T as Simd>::Simd: Add<<T as Simd>::Simd>,
    <T as Simd>::Simd: Sum<T>,
    <<T as Simd>::Simd as Add<<T as Simd>::Simd>>::Output == <T as Simd>::Simd,

This is supported on crate feature compute_aggregate only.
