feat: add examples of Rust and TypeScript (#53)
* feat: demonstrate rust client/server * feat: demonstrate TypeScript node client * feat: add typescript server * refactor: remove non-functional cc toolchain Rust depends on having one that works. We can find a more surgical way to prevent protoc cc_binary from getting built. * chore: missing file * refactor: move to tools
