www/py-lia-web: New port

Write once, run everywhere - A universal web framework adapter for
Python that lets you write code once and use it across multiple web
frameworks.

Lia provides a unified interface for common web framework operations,
allowing you to write framework-agnostic code that can be easily adapted
to work with FastAPI, Flask, Django, and other popular Python web
frameworks.
