Add a Classification Report

[aaly20]

Hi all, this is my first time posting a question on Github ever...

Why not add a Classification Report similar to SKLearn's? The main attractions in SKLearn's version is that it allows me to add class names so that the dict output is named (i.e. F-1, P/R, acc, etc... per class name) -- this makes logging more intuitive when I'm using an experiment tracker like Weights & Biases.

Let me know your thoughts. Thanks!
