Update Benchmarks

[minecrawler]

The bench suite needs to be current state of the art, and add more benchmarks. It's based on an old version of the rust ecs benchmark...

At the same time, sim-ecs should now be integratable into other benchmarks, which work step-by-step (which is synthetic and has nothing to do with real applications..... but whatever), so maybe sim-ecs could be part of other benchmark suites as well and get more visibility from there.
