@livekit/rtc-node is not compatible with Cloudflare Workers

[Shakahs]

@livekit/rtc-node relies on a NodeJS binary extension to do the actual WebRTC signaling.

Cloudflare Workers doesn't support binary extensions, so @livekit/rtc-node does not work on Cloudflare Workers.

Cloudflare does support WASM, WebRTC works in WASM (there are other libraries doing it), and the LiveKit WebRTC binaries are written in Rust, which can compile to WASM. So I think there is a path to resolving this by moving to WASM.
