1.2.1

Bug fixes

• Introduce a message if a station ID is requested but files are not found
  on the server. This is in response to an inquiry from John Paul Bigouette
  where a station is reported as having data in the inventory but the files do
  not exist on the server.

• Fix bug that removed a few hundred stations from the internal GSODR
  database of stations in the data-raw files.

Minor changes

• Clean documentation, shortening long lines, fixing formatting,
  incomplete sentences and broken links

• Clarify the reasons for errors that a user may encounter

• Update internal databases of station metadata

• Clean up this file
