fix deprecation warning in standard dataset

Hi @nrkarthikeyan, can you share how to reproduce the warring message?

[nrkarthikeyan]

Hi @autoih, the following steps work in my machine

conda create -n myenv python=3.7
conda activate myenv
pip install aif360

and from inside python:

import aif360
from aif360.datasets import AdultDataset
data = AdultDataset()

This is the message I get

Custom datasets cannot be used - NotImplementedError being raised.

Nvm - packages on PyPi are just a little outdated.
