Show HN: Hnsqlite: hnswlib and SQLite integrated for text embedding search

Hnswlib is a simple, performant vector search library that is a great choice in many of the same set of scenarios where sqlite is a great choice for other data.

With hnsqlite I integrate these two powerhouses and add support for filtering metadata at embedding search time. While working through several LLM projects I found this to be very useful for self-hosted projects up to a reasonably large size (at least 5-10 million embeddings).
