YouTube Transcript API  Upgraded to 1.1.0 ,fixed the issue of not being able to access YouTube videos.

https://github.com/jdepoix/youtube-transcript-api/releases/tag/v1.1.0

Refactored the way the captions json is retrieved from scraping it from the /watch html to fetching it from the innertube API

Added a new exception called PoTokenRequired, which will be raised if timedtext urls are encountered that require a PO token, such that we get feedback from users ASAP if this happens again
