Restructure embeddings

[NickM-27]

Proposed change

This PR removes the embeddings encapsulation from embeddings context and replaces it with a ZMQ proxy. This ensures that only one process interacts with the model so the model is not loaded multiple times.

I am not sure where to relay this but using Safari on an iphone since the change from chromadb, explore page works fine one first load but when the page is refreshed it seems to stall out. I have to navigate to another page other than explore and then return back to it. If there is a better place to report let me know. Also GPU embeddings great. This model really makes it usable. With 60 or so odd tracked objects its very little cpu and gpu.

there are a number of problems currently, not sure if embeddings are actually working currently
