The progress Event is emitted with an object argument with the following keys:

• dataWritten: size of downloaded data in bytes
• filesize: size of the target file in bytes
• progress: an estimation of the progress percentage
• speed: an estimation of the download speed

    Dl.on("progress", function(progress){
       console.log('Downloaded: ' + progress.pregress + '%'); 
    });
