feat: Add imagemin-webpack plugin/loader (#87)

Much more recent than [image-webpack-loader](https://github.com/tcoopman/image-webpack-loader) and [imagemin-webpack-plugin](https://github.com/Klathmon/imagemin-webpack-plugin) and boasts:

* Granular dependency installing (good for CI + bloat)
* Both plugin + loader to support multiple spots for using images
* Company supported vs individual
