Add config for zype extractor

[lyarenei]

Add a configuration for Zype extractor. This one is used by Nebula and possibly by some other platforms, but I'm not aware of any.

A sample JSON for reference, if you want to check: https://pastebin.com/cuxZpa9C
That one is then converted to this nfo: https://pastebin.com/P0iAsiNJ

I'm not sure about the description, as it can get pretty bloated as you can see. While that itself is not a problem, I guess not many clients wouldn't do correct parsing to show it correctly (Jellyfin doesn't unfortunately). In my current setup, I just remove it.

Also, I think that these configurations are not needed, unless I'm overlooking something. As the json output should be always the same (it'd be the job of the extractor to properly fill the data). Unless the extractors are allowed to write custom stuff into the json file.

Thanks for contributing!

You are correct that the json output should be similar, the point of the custom extractors is to allow for custom stuff to be added to json files as not some properties may or may not be implemented by certain extractors.

I'm in the process of revisiting this project and changing the flow to work better. Thank you for your interest!
