This is PR #3 for this feature. It is very close to the previous one, just
"rebased" on top of the Lucene93 Codec. In this PR I moved the new vector
utility methods as package private in util.hnsw so they would be easier to
change in the future. I did not attempt any loop-unrolling optimizations. I
have tried some incubating vector api implementations, but nothing is ready to
share. I re-ran luceneutil tests, and will open a separate PR for adding
support for this format to luceneutil. Results continue to look promising
