I needed a quick solution for using HNSW in Go and found this package nice, but noticed that it forces `ef` = `efConstruction`. I'm optimizing for a use case where I build an effectively static index. Build time doesn't matter to me but query speed and recall do. So I want to be able to set `efConstruction` high but keep `ef` where it is. I've left this behaving in exactly the same manner as before as the default.
