Bugfix/deprecate decode tag number and value (#481)

* added or updated secure the BACnet primitive value decoders - the core codecs - named bacnet_x_decode(), bacnet_x_application_decode() and bacnet_x_context_decode where x is one of the 13 BACnet primitive value names.  The updated API includes an APDU size to prevent over-reading of an APDU buffer while decoding.  Improved or added unit test code coverage for the BACnet primitive value decoders.

* marked the insecure decoding API as 'deprecated' which is defined in src/bacnet/basic/sys/platform.h and can be disabled during a build. 

* added secure decoders for BACnetTimeValue, BACnetHostNPort, BACnetTimeStamp, BACnetAddress, and Weekly_Schedule and improved unit test code coverage.

* improved test code coverage for BACnet objects and properties.

* secured AtomicReadFile and AtomicWriteFile service decoders and improved unit test code coverage.

* secured BACnet Error service decoder and improved unit test code coverage.
