#' Download and create a list of terra rast objects of CRU CL v. 2.0 climatology elements
#'
#' This function automates downloading and importing CRU CL v. 2.0
#' climatology data into \R and creates a list of \CRANpkg{terra}
#' [terra::rast] objects of the data. If requested, minimum and maximum
#' temperature may also be automatically calculated as described in the data
#' [readme.txt](https://crudata.uea.ac.uk/cru/data/hrg/tmc/readme.txt) file.
#' Data may be cached for later use by this function, saving time downloading
#' files in future using this function.
