Fixed writing to the Channel object when no member value coercion was required. (#1176)

Browse Source 
* Updated documentation for encode functions to accurately describe return values (0 on error instead of BACNET_STATUS_ERROR)

* Expanded property support, removed INPUT object types, added fallback encoding for non-coerced data types, and updated error handling in ReadProperty of present-value to check for 0 instead of BACNET_STATUS_ERROR.

* Expanded the validation tests and increased test code coverage.
