error running `estimate_R_cl()` for `prm.daily$method = "linear"` even though JAGS installed

[papsti]

suppressWarnings(j <- runjags::testjags(silent = TRUE))

comes back with an error of a file not being found, but this shouldn't even be triggering if method = "linear"

workaround for creating ms fig:

• [x] don't check for JAGS if daily inference method is linear
• [x] stick popsize argument in prm.daily since it doesn't need to be specified unless prm.daily is not NULL and prm.daily$method == "renewal"
