Steve Karg f61f4300be Feature/add create object service (#476)
Added BACnet CreateObject and DeleteObject services

* refactored codec for BACnetPropertyValue into bacapp module
* added unit tests for BACnetPropertyValue
* refactored COV and Events to use BACnetPropertyValue codec API
* added unit tests for COV
* added overrun safe decoders for tag numbers and boolean context
* added unit tests and codecs for CreateObject and DeleteObject services
* added APDU service handers and senders for CreateObject and DeleteObject services
* added command line apps bacco and bacdo for CreateObject and DeleteObject services
* added CreateObject and DeleteObject service handling in example server app and device object
* added new BACnetRejectReason, Error Class, and BACnetAbortReason enumerations and conversions
