DSC Keybus Interface
Functions used by all sketches to track the security system status. These
are the most commonly used status data by the example sketches.
Sketches can be extended to support all Keybus data (as seen in
dscKeybusPrintData.cpp) by checking panelData[] - see the Unlocker
sketch for an example of this.
If there is a status that is not currently being tracked and would
be useful in most applications, post an issue/PR:
https://github.com/taligentx/dscKeybusInterface
