hnsw_rs - Approximate Nearest Neighbor - before running detections

[JeffGillin]

hnsw_rs -
run it to narrow down possible objects before sending info to rapier (on much smaller set of coordinates)
Update: Rapier uses Sweep and Prune (SAP) in broad phase, which I just now learned about - seems efficient so this post is moot, plust need to re-built index each frame with ANN.
