* [WIP] hooked up basic video downloading; starting work on metadata

* Added metadata model and parsing

Adding the metadata model made me realize that, in many cases, yt-dlp
returns undesired input in stdout, breaking parsing. In order to get
the metadata model working, I had to change the way in which the app
interacts with yt-dlp. Now, output is written as a file to disk which
is immediately re-read and returned.

* Added tests for video download worker

* Hooked up video downloading to the channel indexing pipeline

* Adds tasks for media items

* Updated video metadata parser to extract the title

* Ran linting
