This PR and trixi-framework/PointNeighbors.jl#74 yield a ~3% speedup on a Threadripper 3990X and a ~42% speedup on an Nvidia H100. Interestingly, there is no difference on an Nvidia RTX 3090 with FP64 (probably limited by something else), but it benefits even more from inbounds on FP32 with a 60% speedup.
