Testing with Pydgin

For more flexibility in the future it would be good to modify VisualRandomTestGen to use Pydgin simulators: https://github.com/cornell-brg/pydgin.

That would make it easier to test arbitrary instruction sets.

I suppose also a more long-term project would be to re-implement Pydgin simulators directly in Visual2 so that Pydgin definitions could directly generate instruction parse and simulation.

Start by locating VisualRandomTestGen and reviewing how it currently performs simulator-based testing. Read the linked Pydgin project to determine the integration boundary; done would mean VisualRandomTestGen can test arbitrary instruction sets through Pydgin simulators. Treat direct reimplementation of Pydgin simulators in Visual2 as a separate long-term scope.
