VPQ doesn't exist. This was bad naming.
VQ is a very primitive method that is not used for vector search.
use_vpq param should be renamed "train_coarse"
Only PQ is used for vector search.
PQ is kmeans cluster assignment on each fragment of the original vector after the original vector is split into fragments.
