[BUG] Generate proper Python stubs

[NikilXYZ]

Describe the bug
A clear and concise description of the bug.
Python API doesn't have stubs which means that IDEs have no idea what functions are even available.

Steps/Code to reproduce bug

Expected behavior
A clear and concise description of what you expected to happen.
When I type cvcuda. in my IDE (like VS Code) I expect it to show all the options for the API including the docstrings that match the help text which I can see when running help(cvcuda.osd_into) or whatever for any functions. Also osd_into in particular isn't even documented on the API website but it's an important and useful feature (don't remove the function!).

Environment overview (please complete the following information)

• Environment location: [Bare-metal, Docker, Cloud(specify cloud provider)] installed w poetry and pyenv. IDE VS Code
• Method of cuDF install: [Docker, pip, or from source] poetry
  • If method of install is [Docker], provide docker pull & docker run commands used

Environment details
Please run and paste the output of the cvcuda/print_env.sh script here, to gather any other relevant environment details
That file doesn't exist in the python installation from pypi cvcuda-cu12 using version 0.16.0 so I can't even run this

Additional context
Add any other context about the problem here.
In my pyenv, these are the cvcuda files that I see:

and this is what is in the init
