• tweaks to benchmark script

PR for https://github.com/GoodBoyDigital/mini-runner/issues/4

Will support https://github.com/pixijs/pixi.js/issues/3835

My goal was to make these changes, while matching the benchmarks in master, and clearly an extra object lookup is losing some speed. I think I'll just go with two arrays. With the changes as they are now, these are the benchmarks, I'll post more with the new changes.

Ok, got it, now these are the benchmarks... There does seem to a be a tiny fraction of more consistency with the reverse while loop, but nothing really measurable from my runs. So this is my PR for now, same performance, but with listener priority order!
