Description

Currently, convergence diagnostic functions are defined in monitor.R. These are mostly the same as what is in the posterior package, but there are some updates in posterior package that have not been added to monitor.R. To reduce amount of duplicate code and to unify the diagnostics between rstan and cmdstanr, it would be good to switch to use the functions directly from posterior package
