dataclasses needed in requirements

Got an error after installing the latest version:

ModuleNotFoundError: No module named 'dataclasses'

resolved with: pip3 install dataclasses

Apologies for this, dataclasses are included in python 3.7+, and unfortunately we have not been testing with lower versions of python.

We will fix-up for backwards compatibility.
