Thanks

I reverted this PR, because for some reason onProgress was throwing some error

[DaddyFrosty]

What's the error?

[fawazahmed0]

Here's the error

C:\Users\nawaz\Documents\GitHub\youtube-uploader\dist\upload.js:125
            videoJSON.onProgress(progress);
                      ^

Oh shit, when I went to bed I made a last change to send a 0% progress event upon starting the upload, and I forgot to make the if statement a block, and so it was calling code it shouldn't for a better explanation look at the changes but this should work.
