This shows that 32x compression just works and we should not add on_disk here

Added both just for sake of transparency. For some data sets, the re-scoring does not significantly help.

| Interestingly, for this dataset, the on-disk approach with rescoring produces similar recall to the in-memory approach without rescoring, but the in-memory approach is substantially faster. This is most likely because the Cohere v3 model has been optimized to work very well with binary quantized data (see [this blog post](https://cohere.com/blog/int8-binary-embeddings)). | ||

Line 260: We haven't actually referenced ANN prior to this. Instead of "ANN approach", do we mean "nearest neighbor approach"?
