   @ChrisHegarty have you seen a significant performance regression on 
MemorySegments & JDK22?
   
   Doing some testing, I updated my performance testing for this PR to use 
JDK22 and now it is WAY slower, more than 2x slower, even for full-byte.
   
   For int7, this branch is marginally faster (20%) with JDK21, but basically 
2x slower on JDK22.
   
   
   I wonder if our off-heap scoring for `byte` vectors also suffers on JDK22. 
The quantized scorer for `int7` is just using those same methods.
