Currently the HNSW codec does too many things, it not only indexes vectors, but stores them and determines how to store them given the vector type. This PR extracts out the vector storage into a new format `Lucene99FlatVectorsFormat`, additionally a "flat" version of `KnnVectorsFormat` is added called `FlatVectorsFormat`. This allows for some additional helper functions that allow an indexing codec (like HNSW) take advantage of the flat formats. Additionally, this PR refactors the new `Lucene99ScalarQuantizedVectorsFormat` to be a `FlatVectorsFormat`. Now, `Lucene99HnswVectorsFormat` can accept either a `Lucene99ScalarQuantizedVectorsFormat` to use int8 quantized vectors or `Lucene99FlatVectorsFormat` for raw vectors. -- This is an automated message from the Apache Git Service.
