`play` · `0x3D` · **clientbound** (server → client)

Sends a ping with an int `id` that the client must answer with a serverbound Pong containing the same id. The server can use it to wait for the client to process all earlier packets. The client responds immediately.

Sent by the server, read by the client. Listen for it with `client.on("Ping", (data) => …)` on the receiving side.
