Add webtransport/webrtc/websocket support

[ValorZard]

This is necessary for games that want high performance networking.

Tbh between the two, I'd recommend webtransport, as it has a smaller surface area and has better performance overall. The downside is the API technically isn't stable yet, but from what I hear it should be stabilizing pretty soon.

Yeah I agree that Webtransport would definitely be way easier to add in & expose through the JS api.

I do think that for proper compatibility in the future, WebRTC (& Websocket) APIs would also need to be exposed at some point, but these could all be separate PRs.

@Flux159 from what i can tell, adding websocket api would be about as easy (if not easier) than webtransport.

@ValorZard Made a first attempt at WebTransport support in version 0.1.4. Docs are here and example code is in this examples/webtransport including a rust based server to test with. I've only tested the basics using that example, but let me know if there's anything missing if you get the chance to test it out (will probably need to update the prebuilt binary if you have a version older than 0.1.4).
