prepo IPrepoService accurate parsing for report (#905)
* prepo IPrepoService accurate parsing for report

I've found they use msgpack for the report, so I've added a nuget package and deserialize the report in the right way.

Close #838

* jD requested changes

* Change nuget to MsgPack.Cli

* Use var instead of explicit cast
