v1.2.0

Major changes

• Remove ability to export files from get_GSOD() to slim down the package
  dependencies and this functions parameters. Examples of how to convert to a
  spatial object (both sp and sf are shown) and export ESRI Shapefiles and
  GeoPackage files are now included in the vignette.

• As a result of the previous point, the sp and rgdal packages are no longer
  Imports but are now in Suggests along with sf for examples in the GSOD
  vignette.

Bug fixes

• Fix a nasty bug where GSOD files downloaded using Windows would not untar
  properly. This caused the get_GSOD() function to fail. Thanks to Ross Darnell,
  CSIRO, for reporting this.

• Correct options in "GSODR use case: Specified years/stations vignette" on line
  201 where file was incorrectly used in place of path. Thanks to Ross
  Darnell, CSIRO, for reporting this.

• Correct documentation for reformat_GSOD()

Minor changes

• Update internal databases of station metadata

• Vignettes contain pre-built figures for faster package installation when
  building vignettes
