Refine data handling

[trangdata]

#211 (comment):

get_coverage <- function(entity = NULL) {
  utils::data("oa2df_coverage", envir = environment(), package = "openalexR")
  oa2df_coverage <- oa2df_coverage

An alternative to utils::data() that's less side-effect-y is to use oa2df_coverage <- get("oa2df_coverage", envir = asNamespace("openalexR")).

I think we can do:

get_coverage <- function(entity = NULL) {
  oa2df_coverage <- getExportedValue("openalexR", "oa2df_coverage")
