decide which ECS to use

[andrewgazelka]

I think we should do a lot of research.
I like evenio but I think we might need a multi-threaded ECS at some point.
At the same time we need to make sure it works properly. Often these ECSs have a lot of overhead.

look at valence-rs/valence#596

Here is a list of some, that i found in a quick search. But i didn't take a close look yet.

Parallel ones according to readme:

https://github.com/amethyst/specs
https://github.com/amethyst/legion
https://github.com/Bergmann89/async-ecs

Need to find out if they are Parallel or not:

I'm also not completely against using bevy esp since I think they have an event feature (although it is unstable possibly?)

[andrewgazelka]

also alternatively could try to improve evenio

[andrewgazelka]
