Adds the function `%contains_any`, and list support in a tilda override subscription. The end-goal of these features are to more easily add a title exclude list, like so:
```
__preset__:
filter_exclude:
- "{%contains_any( %lower(title), exclude_title_strings )}"
...
Jellyfin TV Show by Date:
~History Documentaries:
url: "https://..."
exclude_title_strings:
- "trailer"
- "preview"
```
A proper prebuilt preset or built-in functionality will follow this change.
Adds generic `filter_include` and `filter_exclude` plugins in anticipation for function script usage. Will detail it more with official docs at a later time!
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.
