loadExtractor: support optional extraInfo for dubbed/subbed info

[Kraptor123]

Describe your suggested feature

At the moment loadExtractor only accepts a URL. If it accepted an optional extraInfo (or extraName) parameter, we could display extra infos like “dubbed” or “subbed” in titles improving user clarity and developer workflow without modifying existing extractors.

• My suggestion is NOT about adding a new provider
• I have searched the existing issues and this is a new ticket, NOT a duplicate or related to another open issue.

loadExtractor already allows you to provide custom callbacks, so you can write a callback that adds that metadata before returning the modified link.
