Progress callback seems to be broken.

Using 9.6.4

Traceback (most recent call last):
  File "C:\Scripts\YouTubeDownload\qt_assets\tabs\downloader.py", line 203, in download_streams

I'm unable to replicate this issue.
What was the command you were trying to run?

@jslay88 the on_progress handler interface had a breaking change as part of implementing fast download. I didn't do a great job documenting at the time, updated in : aba400f
I also made a YTD PR for this change.
