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 --------- Co-authored-by: Steve Karg <skarg@users.sourceforge.net>
