FastAPI-based API for generating QR codes with optional image inclusion. It supports both base64-encoded data and plain text. The API is designed to be fast, efficient, and easy to use, making it suitable for a variety of applications.

• Generate QR codes with optional image inclusion.
• Support for both base64-encoded data and plain text.
• Dockerized for easy deployment.
• Asynchronous HTTP requests with aiohttp.
• Utilizes caching for improved performance.
