Image Deformation Using Moving Least Squares

Rust implementation of the paper "Image Deformation Using Moving Least Squares", Schaefer 2006.

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 warpedimgaffine = mlsimage::reversedense(&img, controlssrc, controlsdst, mls::deform_affine); ```
