misc/wthrr: update to 0.2.0

New Features:
- multilang support
- option to disable greeting message

Breaking Changes:
- temperature units now use enum the values `celsius` | `fahrenheit` instead of
  the weather json response string values `°C` `°F`
- if Fahrenheit is your default temperature unit, you might need to save your
  default config again
- lots of improvements behind the scenes for better cohesiveness and defect
  prevention
