I have added the change for using uroman as optional dependency, just want to know if it's correctly implemented.

Super first draft @nandwalritik! It's very close to being ready 🤗

My only issue with the PR is regarding backwards compatibility (explained below). Otherwise, my only request is slightly more verbose installation instructions in the docs.

Other than that, the PR looks great!

Just one doubt here, when I was installing uroman, It requires python version >=3.10. Do we need to mention it somewhere?
