Basically a copy/paste of whats in warp.
Example usage:
```rust
use tower_web::{prelude::*, ws::{ws, WebSocket}};
let app = route("/ws", ws(handle_socket));
async fn handle_socket(mut socket: WebSocket) {
while let Some(msg) = socket.recv().await {
let msg = msg.unwrap();
socket.send(msg).await.unwrap();
}
}
```
