Improved pipeline: download and process chat to build youtube video description

[patcon]

Hi! I have a similar script that actually downloads the zoom chat as well, and uses that to build a table of contents with deeplinked timestamps in the youtube video description.

E.g., typing a zoom comment like /section: conference planning update would make that show up at bottom of youtube description as:

Some video description...

Table of Contents:
00:00:00 start
[...]
00:13:23 conference planning update
[...]

This also adds visual chapters to the video's progress slidee and sidebar, so it's a nice touch, and easy to admin by everyone in the chat.

Any suggestion on how to augment this tool to support that?

Note: i actually have some more advanced stuff too that I might port over, like cropping the video with a specific start and end-time (incl transposing timestamps), pausing and unpausing to go on- and off-camera. (I've also done some work with a CLI video editor called editly, which opens up other neat options!) It's a pretty versatile tactic, like turning shared chat into a command line :)
