Using this project on Windows OS without docker

I'm using the Windows OS, and I don't like using docker for build and test this project.
So when I ran it showed me an error with `ffmpeg` path.

I fixed it with the way:
1. Add package `@ffmpeg-installer/ffmpeg` with `npm i -D @ffmpeg-installer/ffmpeg`
2. Add it to youtube.js like this

I think it may help someone who is don't like the docker like me :v
