Update to bevy 0.7

[ErnWong]

Fixes #26

Remaining tasks: Add an in-tree example that uses crystalorb-bevy-networking-turbulence crate to test that it still works.

Also todo: upgrade wasm bindgen version to fix clippy errors with the demo. Making it part of this pr as it seems like it makes sense to bundle with the rust edition upgrade.

Tested using https://github.com/vilcans/orbgame and it seems to work.

Since we are looking to replace our bevy plugin with one that has better bevy integration (#14), I probably won't add a playable bevy example for crystalorb-bevy-networking-turbulence into this repo. (There's already a short compilable example in that crate's readme, but that's not technically playable).

Once the next version of CrystalOrb gets released with this changes, I might make a PR for orbgame with those changes I used to test this PR.

Oh rip, I'm too slow. Bevy 0.7 is already out. https://bevyengine.org/news/bevy-0-7/

BTW, https://github.com/smokku/bevy_networking_turbulence is unmaintained. I would suggest to consider using https://github.com/lucaspoffo/renet instead.
