add more basic scenarios

[priamai]

Hi there, this project is awesome, I am wondering if would be possible to add more basic examples for people to get started such as the creditcard fraud example from counterfit. Cheers.

Hello! There has been growing interest for additional basic examples. We haven't added text-based or tabular data (as in creditcard fraud) before, which require different threat models in the input space, so those are less likely to be added in the next release, but something that is on the roadmap.
