Downloads a file and returns its content directly, without leaving a
copy on disk. These are the analogues of
googledrive::drive_read_string() and googledrive::drive_read_raw().
Examples
if (FALSE) { # \dontrun{
pd_read_string("data/mtcars.csv") |> read.csv(text = _)
pd_read_raw("images/logo.png")
} # }
