Similarity search library

## Why it's here

Meta's battle-tested ANN library. Use it for maximum recall and speed inside your own process rather than as a service.

## Using it

See the project README in the fetched source:

```bash
./fetch-sources.sh ./sources
tar xzf ./sources/faiss.tar.gz -C ./sources
```

This component is a library, not a service - install it into your own application environment.
