requires redis npm package even when using ioredis

[derevnjuk]

When using @socket.io/redis-streams-adapter with ioredis, the application fails to start due to an unresolved module error. It appears that redis npm package is required, despite using ioredis.

Steps to Reproduce:

1. Set up a new project with the dependencies listed below.
2. Use the provided code snippet in main.ts.
3. Run the project.

Here is a minimal reproducible example:

// main.ts
import { Redis } from "ioredis";
import { Server } from "socket.io";
import { createAdapter } from "@socket.io/redis-streams-adapter";

const redisClient = new Redis();

const io = new Server({
  adapter: createAdapter(redisClient)
});

io.listen(3000);

{
  "name": "test",
  "dependencies": {
    "@socket.io/redis-streams-adapter": "0.2.1",
    "ioredis": "5.2.6",
    "socket.io": "^4.7.5"
  }
}

Expected Behavior: The adapter should work usingioredis without requiring the redis package.

Actual Behavior: Throws an error stating that the redis module cannot be found.

Logs:

This should be fixed by https://github.com/socketio/socket.io-redis-streams-adapter/commit/a2f3f5aeaf2a1b171bc094d0fe3b9fb2996fcd54, included in version 0.2.2. Thanks for the heads-up!
