Description

Summary:

Recent versions of loo have a moment_match argument, but the loo method in rstanarm cannot utilize it

Description:

https://mc-stan.org/loo/articles/loo2-moment-matching.html

Can we squeeze this into the rstanarm CRAN release? I think we just need to get the unconstrained draws from the CSV like we do with the bridgesampling method and then provide the functions for loo like we do with rstanarm now.
