Organize calibration, IC, and scoring rule modules.
Organize calibration, IC, and scoring rule modules.

Some modules have names that weren't super descriptive of their contents. I organized it following the different set of uncertainty metrics. Namely this:

+ Merges ECE and Bayesian ECE into calibration.py.
+ Merges mutual information and PPC into information_criteria.py.
+ Merges Brier and CRPS into scoring_rules.py.
