v0.3.2 Speed up index creation by more than 60x

We discovered two thing making index creation unnecessarily long:

1. Instead of using KMeans++ to initialize, just do random initialization
2. Turn of BLAS on macOS because it turned out to be super slow

On macbook air, index creation goes from 25min on sift1m to 24s.
On Ubuntu, it's roughly a 6x speedup.
