Conda Forge `staged-recipes` utility scripts

new-cran-pkg.sh

#!/usr/bin/env bash -l
#'   Usage: `bash -l new-cran-pkg.sh {r-package}`

#'  Notes: Should be located in and run from a `staged-recipes` clone prefix.
#'         `git remote -v` should show `origin` set to a personal fork
#'         and `upstream` set to 'git@github.com:conda-forge/staged-recipes.git'.
#'         CRAN package name should be prefixed with 'r-' and given in all lowercase.
