Library is not compatible with latest version on socket.io 4.7.4

Hi, library is no longer compatible with latest socket.io. (4.7.4) In latest version of socket.io there is list reserved events : https://github.com/socketio/socket.io-parser/blob/9f76ea22b41feeade0c8819dbf3c16fd07becc2a/lib/index.ts#L11

/**
 * These strings must not be used as event names, as they have a special meaning.
 */
const RESERVED_EVENTS = [
  "connect", // used on the client side
  "connect_error", // used on the client side
  "disconnect", // used on both sides
  "disconnecting", // used on the server side
  "newListener", // used by the Node.js EventEmitter
  "removeListener", // used by the Node.js EventEmitter
];

In this library list of events looks like this:

const List events = [
  'connect',
  'connect_error',
  'connect_timeout',
  'connecting',
  'disconnect',
  'error',
  'reconnect',
  'reconnect_attempt',
  'reconnect_failed',
  'reconnect_error',
  'reconnecting',
  'ping',
  'pong'
];

as you can see we are missing disconnecting event. Now flutter apps send disconnecting event as EVENT type: 2, but correct type is 1.

As a result, server side socket.io crash:
