Load hnswlib index from file which was serialized from a HNSW index. NOTE: When hierarchy is NONE, the loaded hnswlib index is immutable, and only be read by the hnswlib wrapper in cuVS, as the serialization format is not compatible with the original hnswlib. Experimental, both the API and the serialization format are subject to change.
