refactor: bevy (#882)

This is an experiment

Related: valence-rs/valence#685

## Why switch from flecs to Bevy

- https://github.com/Indra-db/Flecs-Rust is not widely used; we could
get more contributors who are familiar with Bevy.
- https://github.com/Indra-db/Flecs-Rust has some current usability
issues for Rust that need to be improved upon.

## Why stay in flecs

- More performant
- Has ability of us adding scripting language on top in non-Rust
- Overall better design (at least for non-Rust). I expect flecs to
always be ahead of Bevy in terms of its progress. Also less of a chance
we get roadblocked by some Bevy design feature.

---

Issues that need to be resolved:
- in Bevy not everything is an entity. This makes some things annoying.
For instance, I am unsure how `system-order` (which is core to hyperion)
will work


https://github.com/hyperion-mc/hyperion/blob/9b8c3d06124da811896a479e7d3c8dceb5f55349/crates/system-order/src/lib.rs#L1-L146

`system-order` is used for re-ordering packets once they reach the
proxy. I definitely feel like flecs has fewer things that would hard
roadblock us... however sadly flecs rust has some quality of life issues
that can be annoying
