`PubSubx` is a lightweight and flexible publish-subscribe (PubSub) library built on top of Elixir's `GenServer` and `Registry`. It allows processes to communicate by subscribing to topics and receiving messages when they are published. This is useful for decoupling components in your Elixir applications, enabling easier scalability and maintainability.

## Features

- **Subscribe/Unsubscribe**: Processes can easily subscribe or unsubscribe from topics.
- **Publish**: Messages can be published to any topic, notifying all subscribed processes.
- **Dynamic Topic Management**: Topics are created and removed dynamically based on subscriptions.
- **Process Monitoring**: Automatically handles the removal of subscriptions when processes terminate.

## Installation
