* Add low and high trim fade functionality to lighting command operations
* Refactor lighting command override functions and fix operating and normalized range.
* Add physical range clamping function and update related clamping logic
* Added Blink.Callback and Blink.Priority to support end-of-blink actions for WARN_OFF/WARN_RELINQUISH. The Blink.Callback is invoked when a blink sequence ends or when a new command interrupts a WARN_OFF/WARN_RELINQUISH in progress.
* Added Lighting Output (LO) WARN_OFF/WARN_RELINQUISH post-egress priority array handling using the Blink.Callback
* Fixed lighting output object lighting-command last-on-value to only
be updated with the last value of the Present_Value property that
was greater than or equal to 1.0%, keeping in mind that the Present_Value
shall indicate the target level of the operation and not the current
value.
* Fixed Lighting_Command to ignore write priority and use its own.
* Fixed BACnetLightingOperation reserved range.
* Refactor overridden into the lighting command module. Added Overridden status flags API. Added Lighting Output API to implement a momentary override to the output that is cleared at the next lighting command. Integrated lighting command overridden behavior into the lighting output object.
* Added Trim_Fade_Time, High_End_Trim, Low_End_Trim, Last_On_Value and Default_On_Value properties to lighting output.
Added TRIM_ACTIVE flag to lighting command. Added Last_On_Value and Default_On_Value to lighting command for restore and toggle.
* Refactored lighting command operations from the lighting output object, and added unit testing. Integrated the result back into lighting-output object.
