Added requirements.txt file for python dependency management

[AK-Github-0]

Summary

This pull request adds a requirements.txt file to help users easily install the required Python dependencies using pip.

Details

• Created a requirements.txt file listing all the Python packages used in the project.
• This makes it easier for new contributors and users to set up the environment quickly via pip install -r requirements.txt.

Motivation

Many open-source Python projects benefit from having a requirements.txt to standardize dependency installation. It also helps tools and CI pipelines that rely on explicit dependency declarations.

Notes

If there’s a preferred way to manage dependencies in this repo, I’m happy to update the PR accordingly.
