v4.4.2

Enhancements:

• CharactertisticDelegate: Add addValue() method to set HomeKit characteristic value, as if input by user.
• OptionParser: Add tests;
• OptionParser: Add key parameter to to...() static methods;
• OptionParser: Add more functionality:
  • toIntString()
  • toNumber()
  • toNumberString()
  • toAsyncFunction()
  • toClass()
  • toInstance();
• Update developer documentation (work in progress)

Bug fixes:

• JsonFormatter: Handle obejct keys and array elements with value undefined (by not showing the key or element).

Technical:

• Platform: Don't put homebridge-lib version in key for global namespace. Need separate version for heartbeat, UPnP listener compatibility.
• JsonFormatter: Store options in options object instead of in this (which fails to OptionParser.toObject()` test).
• Remove TypeParser; basic functionality now included in OptionParser.
• Implement hap, json, and upnp commands as exported modules, so plugins might install them.
• Update Javascript layout to standard v13.1.0.

Bump dependencies:

• NodeJS v10.16.1 LTS
