Description
I just discovered crps! This is great, I was actually asking about how to compare probabilistic vs non-probabilistic predictions https://discourse.mc-stan.org/t/comparison-of-machine-learning-models-and-bayesian-models/30833 and this is exactly what I needed.
I just noticed that loo_compare and print are not implemented. If it's ok, I volunteer to implement it. I just want to know how would you call the predictions, "elpd" doesn't make much sense. Maybe "ps"? (predictive score)?

Research direction
Start by reviewing the existing crps and loo_crps functionality, then examine how loo_compare and print are handled elsewhere in the package. Resolve the terminology for predictive scores before implementing the comparison and printing behavior; done means both functions support these predictions with agreed output naming.
