Add competition benchmarks for random/world component access

[mlange-42]

Add benchmarks ECS performance comparison for access to components via the world instead of queries (i.e. by entity ID).

I don't recommend this. Arche will be smoked.

Just saying..

[mlange-42]

@captkirk88 Why do you think so, and compared to which ECS implementation?

[captkirk88]

@mlange-42 Are we talking any language? Or just C#?

[mlange-42]

@captkirk88 Arche is not in C#, it is in Go. To be fair and to make the proof easy, it should be Go. But I am not shy of comparing to other languages, too.

However, I would be more interested in what about Arche makes you think so.

[captkirk88]

If you are going to benchmark, then compare across all languages, not just Go. I mentioned C# because it isn't going to win. That's a given. But a overall comparison would showcase the differences between the languages and allow a better picture. I'm just tired of all these comparisons between ECS frameworks always being the same language. It defeats the purpose.

[captkirk88]

It's not a pissing match. It should be a fair and complete comparison benchmark.

[mlange-42]

Would definitely appreciate such benchmarks, but this repo is not the place for that.

Random access benchmarks were added to go-ecs-benchmarks, see section Component random access.
