It downloads binaries for all platforms and architectures instead of downloading according to current system.

Right now my electron app's size increases by 200 to 300MBs just because of ffprobe, you should have a look at ffmpeg-static because that one uses a smart approach it downloads the files according to system - which it does by this line in its package.json

"scripts": {
    "install": "node install.js",
     ...
  }

idk if I'm missing something but yeah this would decrease download time and package size.
