Client.h rename in Vicon Data Stream SDK

[aaronsfox]

As discussed Claudio, it looks like in updated versions (not sure exactly when but at least from v1.7) Vicon has renamed the Client.h file to DataStreamClient.h

I can confirm this, I had to change line 24 in DataFromNexus.h from
#include <Client.h>
to
#include <DataStreamClient.h>
when building the solution in Visual Studio in order to have it successfully build the project without errors.

I have updated the codebase to use the ViconDataStreamSDK 1.9+. It compiles well now, but I still haven't fully tested that everything works fine. I'll keep this open until I add an appropriate testcase.

I have added a Vicon Nexus example which works fine with markers. I will ensure streaming of analogue data is also correct before closing this isssue
