Reduce verbosity of logging by using Homebridge debug mode

[PuzzledUser]

Homebridge logs (for other plugins) are obscured by lots of verbose logging from Away Mode. Relegate many log events to Homebridge Debug (-D) mode — they're still available when needed, but otherwise out of the way.

Replace initialisation dump of JSON timer config with summary of times for each sensor.

Also (perhaps controversially) add a new more compact single line log entry for ON events, rather than details of timers for future OFF (currently on) and ON (currently off) events.

e.g.
[13/04/2023, 21:21:03] [Away Mode] Bed (0): Motion on for 1055s until [21:38:38]

I've (hopefully) made a Pull Request with the specifics.
Cheers
