I wanted to build IVF262144_HNSW32,SQ8, but the estimation of the required memory was way too big.

I think it's important to have those kinds of index in the library since it does not consume a lot of ram when memory mapped and do not compress too much the vectors.

So it's an intermediary between HNSW32 and OPQ_PQ
