List all stanflow dependencies

Usage

stanflow_deps(recursive = FALSE, dev = FALSE, check_updates = TRUE)

recursive: If TRUE, will also list all dependencies.
dev: If FALSE (default), checks for updates in the R-multiverse or CRAN (stable releases). If TRUE, checks the Stan R-universe (dev versions). This is only cogent for Stan packages, and cannot compare two dev versions.
check_updates: Logical. If FALSE, skips checking for remote versions and only reports locally installed package versions.
