prediction_breakdown() plot result may be confusing with default `baseline` choice #39

New to this so please let me know if I'm misinterpreting the functionality!

Currently, the baseline argument to broken() is hardcoded to be "Intercept" and there is no way to modify it. This parameter should be exposed, and the default may lead to confusion because one would expect "final_prognosis" to be equal to the prediction, at least for models with an identity link function. Also, the plot method doesn't tell you what the baseline is, so it's difficult to tell the story of how we got to the prediction (since we don't see the prediction on the plot.)
