Nothing in the archive, it make folder

• Handle the case webkitdirectory / folder + files is not supported (on mobile)
  • Polyfill for webkitdirectory
• Find a way to handle directory, create an object backed with path and content (ex. bottom)

let obj = {
  parent_folder: {
    mockup: {
      "demo.png": 'File buffer as Uint8Array',
      "hey.jpg": 'File buffer as Uint8Array',
    
    },
  },
}

• Explore fflate code source in order to understand fltn function
• Don't compress files that are already compressed
• Move to .zip method instead of .zipSync
