Cannot plot interactions with multiple imputed datasets

Feature request:
cat_plot & interact_plot do not support pooled regression objects (eg. mipo objects). It would be great if it did as there does not seem to be any other package available that would.

Read the cat_plot and interact_plot entry points, then review the linked Stack Overflow question and gist for the pooled-regression use case. Define how mipo objects should be supported and verify that both functions can plot interactions across multiple imputed datasets.
