fix typescript definitions

v.3.0.3

1. SocketIO client options

What happen with old one SocketIOClientOptions?

At this moment works only:

import io, { ManagerOptions } from 'socket.io-client;

const IOOptions: Partial<ManagerOptions> = {
  path: '/seacher',
  autoConnect: false,
  transports: ['websocket'],
};

Write Partial<ManagerOptions> is not good way.

1. Type of io now unknown

If write

import io from 'socket.io-client';
...
this._socket = io(url, IOOptions);

There are will be an TS error for io like

import io
This expression is not callable.
  Type 'typeof import("/mnt/hdd/Projects/home/searcher/node_modules/socket.io-client/build/index")' has no call signatures.ts(2349)

Works only ‘classic’ way:

import io from 'socket.io-client';
...
this._socket = (io as any)(url, IOOptions);

change to

import {io} from 'socket.io-client';

and must (importance) update your server to socket.io 3.0.3, it take all day of my T_T
