   Users should utilize the new 104 scalar quantization format with the 
asymmetric quantization encoding.
   
   When migrating to the new format, the main change will be instead of using 
`new Lucene102HnswBinaryQuantizedVectorsFormat()`, user's should use `new 
Lucene104HnswScalarQuantizedVectorsFormat(ScalarEncoding.SINGLE_BIT_QUERY_NIBBLE,
 DEFAULT_MAX_CONN, DEFAULT_BEAM_WIDTH, DEFAULT_NUM_MERGE_WORKER, null, 
HNSW_GRAPH_THRESHOLD)`
