Download video(s) (first iteration) (#5)

* Updated package.json (and made an excuse to make a branch)

* Video filepath parser (#6)

* Restructured files; Added parser placeholder

* More restructuring

* Added basic parser for hydrating template strings

* Improved docs

* More docs

* Initial implementation of media profiles (#7)

* [WIP] Added basic video download method

* [WIP] Very-WIP first steps at parsing options and downloading

* Made my options safe by default and removed special safe versions

* Ran html generator for mediaprofile model - leaving as-is for now

* Addressed a bunch of TODO comments

* Add "channel" type Media Source (#8)

* [WIP] Working on fetching channel metadata in yt-dlp backend

* Finished first draft of methods to do with querying channels

* Renamed CommandRunnerMock to have a more descriptive name

* Ran the phx generator for the channel model

* Renamed Downloader namespace to MediaClient

* [WIP] saving before attempting LiveView

* LiveView did not work out but here's a working controller how about

* Index a channel (#9)

* Ran a MediaItem generator; Reformatted to my liking

* [WIP] added basic index function

* setup oban

* Added basic Oban job for indexing

* Added in workers for indexing; hooked them into record creation flow

* Added a task model with a phx generator

* Tied together tasks with jobs and channels

* Download indexed videos (#10)

* Clarified documentation

* more comments

* [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
