Describe the solution you'd like
Please provide example code for using the generator from javascript instead of as a CLI.

const ImageResGenerator = require("image-res-generator")

module.exports = function(context) {
const generator = new ImageResGenerator(context.opts.projectRoot)
.withIcon("icon.svg") //optional
.withSplash("splash.svg") //optional
.withPlatforms("ios", "android") //optional
.withAllPlatforms() //reverts the withPlatforms setting
.withOutputDir("res") //ioptional

generator
.makeIcon() // invoke to make icons return self so we can chain with
.makeSplash() // invoke to make splash

}
