[FEATURE]: Ability to use and compare multipe datasets

[mwojtyczka]

Is there an existing issue for this?

• I have searched the existing issues

Problem statement

The framework currently can only handle one dataframe at a time. Ability to handle multiple dataframes will allow to make consistency checks between datasets.

Could potentially leverage existing frameworks, eg. https://github.com/MrPowers/chispa

Proposed Solution

It would be useful to extend the functionality by adding the possibility to compare datasets.
