Progress bar for Gallery-dl?

[AFGreeneye]

Hello, dear developers! I hope all of you are doing fine. Today, I was thinking about writing some code (I'm still a beginner and struggle with Python) to integrate a "Progress Bar" into gallery-dl. The idea is to replace the long list/log of downloaded files with a compact one-line progress bar. Additionally, it would be great to receive a notification if any new files have been downloaded since the last time. So what do you think guys?

This have been requested before, for example in #2873, basically the total amount of files aren't known in advance so a progress bar for the entire download isn't possible.
