How to use ReRank models in LangchainJS?

[gon-martinam]

Hi 👋

I would like to know what possibilities there are of including ReRanking models beyond Cohere (or other well-known ones).

That is, if a new ReRanking model comes out today and I want to test it in my application with Langchain, how should I use it together with my VectorDB?

I've checked the documentation and I think I've not found a way to use a custom ReRanker model or a model I may find in HuggingFace.
