v2.0.1

Bug fixes

• Corrects internal bug that provided a warning message when GSOD files were
  parsed

• Fixes bug where not all files downloaded were cleaned up on the function
  exit when fetching station inventories

• Fixes bug where station inventories from get_inventory() lacked the
  location metadata, i.e. country and other geographic information

Minor changes

• Update vignette to use latest functions from tidyr, i.e.
  tidyr::pivot_longer()

• Update internal station list to latest

• Tidy up documentation, mainly fix functions' title capitalisation

• get_GSOD() checks the number of stations being requested. If the number is

10, the entire annual file will be downloaded and requested stations will then
be selected and returned. This saves time by reducing the number of requests
made to the server. Users should not see any difference other than quicker
responses for a large number of requested stations.

Major changes

• Requires R >= 3.5.0 due to the storage of .Rds files using the latest version
