I ran a simple benchmark which calls `add` or `add_mut` on two primitive
arrays, e.g.,
```rust
let mut arr_a = create_primitive_array::<Float32Type>(5120000, 0.0);
for _ in 0..10 {
let arr_b = create_primitive_array::<Float32Type>(5120000, 0.0);
// arr_a = add(&arr_a, &arr_b).unwrap();
arr_a = add_mut(arr_a, &arr_b).unwrap().unwrap();
}
```
```
array add time: [675.93 ms 676.09 ms 676.28 ms]
change: [-3.2262% -3.0312% -2.8816%] (p = 0.00 <
0.05)
Performance has improved.
```
