Version 0.8.1 aligns the Digital Twin State with the Physical Asset Description: properties, events and actions now carry both a semantic type and a contentType (the format) in the State too.

Key Updates:

• contentType in the DT State: DigitalTwinStateProperty and DigitalTwinStateEvent gain a contentType field (DigitalTwinStateAction already had it)
• New constructors that set both type and contentType
• Deprecations: constructors with only the type are deprecated and will not be supported anymore from version 0.9.0
• Fixes: equals/hashCode/toString of the State and Physical resources now include type and contentType, and several NullPointerException in equals are fixed

No behaviour of the framework changes: the core never interprets type or contentType, it only stores and forwards them, so existing code keeps compiling and running (with deprecation warnings).
