Extract log-likelihood components for likelihood profiling from MCMC samples.
Uses get_posterior to obtain the log-likelihood components.
Examples
pars <- c("tag_ll", "cpue_ll", "sexr_ll", "lf_ll", "prior")
# lls <- get_posterior(object = obj, posterior = mcmc, pars = pars)
# get_mcmc_profile(loglikes = lls)
