Addition of the new IDGI framework to the list of explainability methods

IDGI is a relatively new attribution method described in this paper in 2023

IDGI is a framework that can be applied to any integrated gradients method (BlurIG, GIG etc.) however I propose implementing it for the vanilla integrated gradients method. The implementation of this would exist as a separate class and would not be dependant on the IntegratedGradients class, which would keep the code implementation clean.
The mathematical implementation of IDGI is simple and it is not very compute-intensive

I have opened an issue for the same on Github
I would like to work on the implementation of this framework. Should I go ahead?
