Given data, identify Pi products that are converging

[KomaGR]

Given a stream of data and a Newton invariant, use the Pi product generation passes and then utilize the input data to start evaluating the groups. The identify which are converging to a constant value.

With that information we can try to solve the equations that seem to be true.

Potentially output a Newton description that the Data Checker would "accept" for the data (see #620).
