Adds the ability to toggle whether to use `upload_date` or `release_date` in the date_range plugin, which is used to cull older videos.
```
date_range:
type: "upload_date"
```
If using the Only Recent preset, it will be automatically applied based on whether your season/episode ordering uses release date or upload date.
Closes https://github.com/jmbannon/ytdl-sub/issues/1182
Adds a the new field `breaking` to the `date_range` plugin, to toggle whether an entry breaks subsequent metadata pulls. This is useful to disable if you are grabbing a playlist that may have videos out of order, but still want to apply a date range to it.
A complete gutting of the internals of ytdl-sub to support functions in our variable syntax, in addition to being able to access a yt-dlp entry's .info.json fields using functions. Functionally, ytdl-sub should still look and behave the same from a user-perspective.
With so many lines of code changed (+8927, -2708), no doubt there will be new issues. Please make a GH issue or reach out on Discord if your config/subscriptions break in any way/shape/form.
Details on how to use function support will come soon in the form of proper documentation in our readthedocs.
Bugfix to the prior release. Convert yt-dlp date formats (i.e. `today-2months`) into a date string with format `YYYYMMDD`. This will make it compatible with match-filter syntax
