Our postings use a layout that helps take advantage of Java's auto-vectorization to be reasonably fast to decode. But we can make it a bit faster by vectorizing directly from the MemorySegment instead of first copying data into a long[]. This approach only works when the `Directory` uses `MemorySegmentIndexInput` under the hood, ie. `MMapDirectory` on JDK 21+. Co-authored-by: Uwe Schindler <uschindler@apache.org>

Building
Basic steps:
- Install OpenJDK 21.
- Clone Lucene's git repository (or download the source distribution).
- Run gradle launcher script (
gradlew).
We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.
