[Feature Request] Generic Feed Provider Api

[c128128]

Generic Feed Provider Api

The idea is to create a generic parser and an API that will permit other developers to create custom scripts in JS that will run inside JavascriptCore and parse custom feeds.

Something like Extensions but Generic.

This can be very useful if we want to parse some pages that don't provide a RSS feed like:

1. https://developer.apple.com/documentation/technotes
2. https://www.mongodb.com/docs/realm/release-notes/backend

Some ideas what this should include:

• [ ] An API that will permit developers to write custom parsers.
• [ ] A centralize place where users can add this parsers. (I think something like Cydia.). Where there are some default parsers and custom can be added too.
• [ ] A place where developers can submit their parsers (Maybe with some kind of review).
• [ ] Instructions about how can a developer write and debug a custom parser.

Other ideas are welcome.

P.S: Thank you for your work, the app is amazing.

I think this is basically the same thing as #3385. I'm going to mark this as a duplicate of that. It will have a reference back to this issue that we can review when evaluating #3385.
