Update internal function references (Automatic reference detection coming soon:tm:)

YouTube updated their code (again). I'll figure out a way to make this somehow automatically live patch the code some time

• Fixed broken update (YouTube updated their code)
• Chapter counting algorithm broke (again, YouTube now defers chapter loading)
• Now updates the bar when mouse is hovering directly over the scrubber (the red bar)
• Improve updates by caching scale operations of 0 and 1 (when there are a lot of chapters, it does less updates, making the perf boost even more)

beta release for chapter rendering fix

Whoops, forgot @run-at

## v0.2

Updated because YouTube updated their codebase (this script taps into non-apis unlike YouTube CPU tamer). Expect changes like these to happen frequently

## v0.1
