Add a dependency management file for easier setup

[ShivamGupta-16]

I noticed that the project does not contain a 'requirements.txt', 'setup.py' or 'pyproject.toml' file.
Adding one would make it easier for new contributors to set up the project and install dependencies quickly.

Would you prefer:

1. A 'requirements.txt' file (using 'pip freeze' or 'pipreqs' to list dependencies).
2. A 'pyproject.toml' file (using Poetry for modern dependency management).

Let me know how you'd like me to proceed, and I'd be happy to create a PR!

I wrote this issue in my proposal as well, I think adding a 'requirements.txt' file will help every developer setting on the same page.
