Support throttle option in ClientOptions

[krapie]

What would you like to be added: Support throttle option in ClientOptions when defining clients.

Why is this needed: Throttling update rate on client/doc will prevent both client and server to be overloaded. For example, animating multiplayer cursors may invoke client/doc updates for every 1ms, which will overload both client and server. For more information about animating multiplayer cursors, check this article: How to animate multiplayer cursors

To avoid this, throttling update rate is necessary for both client and server.

Currently liveblocks support this option on client definition. Here's liveblocks API reference:

import { createClient } from "@liveblocks/client";

const client = createClient({
  /* ... other options ... */
  throttle: 80,
});
