Get URLs to Available Radolan Files

Description

Get URLs to available radolan files on the DWD FTP server below this base address: ftp://opendata.dwd.de/climate_environment/CDC/grids_germany. The user can choose between daily records and hourly records that are located at different paths on the server. The paths to the files are not read from the FTP server but generated, given the knowledge of where the files should reside and how they are expected to be named.

  start_daily = "2006-10",
  start_hourly = "2005-06",
  end_daily = format(format = "%Y-%m", lubridate::rollback(Sys.Date(), roll_to_first =
    TRUE)),
  end_hourly = end_daily,
  ...
)
