// It will create the full path in case it doesn't exist
// If the extension is defined (e.g. fileName.png), it will be preserved, otherwise the lib will try to guess from the Data URI
let filePath = './out/path/fileName';
// Returns a Promise
imageDataURI.outputFile(dataURI, filePath)
// RETURNS image path of the created file 'out/path/fileName.png'
