Integrate a Web API into `pgmq` Library

[tavallaie]

I would like to propose the integration of a web API within the pgmq library. Drawing inspiration from successful implementations such as pgmq-rest, it's clear that having a RESTful interface can significantly enhance functionality and user experience.

Proposed Features:

• Simple REST API: Develop a straightforward API for interacting with pgmq, modeled after the elegant setup in the referenced repository.
• Message Operations: Enable functionalities to send and receive messages efficiently through the API.
• Batch Operations: Implement batch processing capabilities, mirroring best practices seen in similar projects for improved performance.
• Queue Metrics & Monitoring: Include tools for monitoring queue metrics directly from the web interface.
• Swagger Documentation: Utilize Swagger to provide clear documentation for the API endpoints, making it easier for developers to integrate and use.
