Replace legacy Youtube-dl with currently maintained yt-dlp

[Aida-Enna]

Replacing the included youtube-dl.exe with a renamed yt-dlp.exe made everything work as expected again and download fast. Based on this, this PR should fix the issue across all platforms with minimal changes, mostly comsetic (youtube-dl -> yt-dlp).

I modified the package stuff to include these as well, although I'm not sure why the python script is saved as a .zip. I also checked and there is a brew package for yt-dlp, so I swapped that as well.

Should fix #67 and #61, although I don't have a build environment set up for this to test it.
