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.
This implements %regex_sub built-in function to enhance string-processing capabilities, allowing users to perform substitutes like:
- removing non-ascii characters
- replacing subsequent whitespace characters with a single whitespace
Thanks @tbabej !
Readthedocs for ytdl-sub is getting a massive overhaul to both look and read like a modernized app. It is still very-much work-in-progress, stay tuned for more!
Huge thanks to @Svagtlys (aka Momo) for driving this
