Option to include modeling object as a returned statistic in ARD?

[ddsjoberg]

Feature description

for functions like ard_regression(), ard_ttest(), etc., should we include an argument to return the ARD with a row for the model object.

• PRO: for regression models, users have access to the object needed to make additional calculations as needed.
  • an aside, need to consider how we can add additional results to the regression modeling object. Thee broom::glance() is a simple default (and easy to make extendable by users). Even if we did add this, how can we distinguish these results from other regression model objects that may appear in the same stacked ARD.
• CON: a modelling object is not something that is generic/readable by other languages, so we need a direct use case before adding it
