Introduce ignoreFailIfHostOff config setting
Some sensors only provide valid readings when the host is powered on.
This change introduces the `ignoreFailIfHostOff` configuration option to
differentiate between unavailable readings based on host state.
- Host OFF: Sensor unavailable is acceptable and will not be treated as
a failure.
- Host ON (running): Sensor unavailable is unexpected, and the failsafe
mode will be triggered.
This ensures that sensors dependent on host power state are handled
correctly without causing unnecessary failsafe triggers during host-off.
Tested on Catalina: failsafe mode is not triggered when the host is off.
- config.json example: add `ignoreFailIfHostOff` for sensors only
available when the host is on.
