Toy image transform

This is a toy project of mine to learn Rust that implements an image transform. The idea is that you take a macro image with the object in question surrounded by a black 2:1 ratio rectangle printed on white paper. The program finds the rectangle (which may be bowed due to lense distortion and rotated) and produces a nicely straightened result image.

TODO: Use interpolation to produce each pixel from its neighbours depending on the fractional location. Come up with a more convincing control point for the middle bezier. Take options for output size Take parameter for output name
