Separated xml serialization model and data structures from CRTProtocol (

#66)

This PR aims to make it easier to replace the xml serialization currently in place.
In order to avoid a circular dependencies we move structures previously defined in RTProtocol.h into Settings.h behind a new namespace qualisys_cpp_sdk. We declare a new serialization and deserialization interface in Settings.h and move the current xml serialization to MarkupSerializer.cpp

A side effect of moving the structures outside CRTProtocol is that enum constants are no longer reachable directly through the CRTProtocol namespace, instead they must be reached through their respective enum name.

Example:

CRTProtocol::RateAllFrames -> CRTProtocol::EStreamRate::RateAllFrames
alt
CRTProtocol::RateAllFrames -> qualisys_cpp_sdk::EStreamRate::RateAllFrames
Added two new interfaces to be implemented by a future serialization solution.
ISettingsSerializer
ISettingsDeserializer
We can consider removing the interfaces after the transition is done to a new serializer.
