So remember when last time I thought “oh no how to do private prefix arrays”?

Well, an hour later and I discovered “Oh, my 2^24 entities can be divided by 256 and then 256 again so I’ll just have to do 3 prefix sums layered one on top of each other on the thread level”

I don’t know what happened but my brand new 8 bit radix pass takes 460+ms. Yay
