Elxvips

Experimental Elixir bindings to libvips for image processing, since it's supposed to be faster than GraphicsMagick/ImageMagick. It is based on the existing Rust bindings to libVips. To make it work you will require libVips and the rust compiler. Please refer to Dockerfile for dependencies.
