Bugfix/property array element zero size (#908)

* Changed BACnetARRAY index validation into ReadProperty, ReadPropertyMultiple, WriteProperty, and WritePropertyMultiple handlers.

* Changed the basic and example objects after refactoring BACnetARRAY index validation into ReadProperty, ReadPropertyMultiple, WriteProperty, and WritePropertyMultiple handlers.

* Added BACnet application decoder that understands that an array element of zero is an unsigned integer tagged value.  Fixes RP and RPM apps when reading the array element zero of arrays.
