[Idea]: Worker pools

### What's your idea?

Implement a async worker pool.

### Why is that needed? How it may be useful?

Sometimes I need to run a lot of tasks, and I split them with chunk() to batches. Will be nice to have a pool of async workers which can peekup work from a queue and start working as soon as as possible. 

### Maybe you have a demo or example?

```ts
TODO
