The optional `rayon` feature enables parallel iterators for the generation of the warped image.

Here is what using the library looks like:

```rust
// Open an image from disk.
let img = image::open("data/woody.jpg")?.into_rgb8();

// Define the source control points.
let controls_src: &[(f32, f32)] = &[
    (20.0, 160.0),
    ...
    (250.0, 369.0),
];

// Define the destination control points.
let controls_dst: &[(f32, f32)] = &[
    (20.0, 250.0),
    ...
    (250.0, 369.0),
];

// Create new warped image.
let warped_img_affine =
    mls_image::reverse_dense(&img, controls_src, controls_dst, mls::deform_affine);
```
