The function `install_load` checks the local R library(ies) to see
if the required package(s) is/are installed or not. If the package(s)
is/are not installed, then the package(s) will be installed along with
the required dependency(ies). This function pulls source or
binary packages from the Rstudio-sponsored CRAN mirror and/or
the USGS GRAN Repository. Lastly, the chosen package(s)
is/are loaded. The function `load_package` simply loads the provided
packages.
