v2.2.23

Bug fixes:

• Only expose accessories for locations from config.json; cached accessories are removed when no longer specified in config.json. See also #14;
• Check status (in body) returned by OpenWeatherMap.

Code refactor:

• Use HttpClient instead of RestClient from homebridge-lib. Under the hood, the dependency on the now deprecated request package was removed;
• Use async/await instead of promise .then();
• Cleanup of old commented code.

Bump dependencies:

• NodeJS v12.16.1 LTS;
• homebridge-lib v4.5.1.
