Categorical Support for Laplace Mecjanism

[grilhami]

Description

Added categorical support for LaplaceMechanism class, which is able to take the cat_feat_idxs and cat_sensitivity arguments.

The SKLearn_Pipeline_Laplace_Mechanism.ipynb notebook has been modified to include examples for categorical support.

How has this been tested?

Run all the code in the SKLearn_Pipeline_Laplace_Mechanism.ipynb notebook after successfully building PyDP.

@chinmayshah99 It seems this conflict has something to do with pyproject.toml. Do you have any idea about this?

I don't see any conflict, but rather addition of a new package. This seems okay.
