Don't save byte[] as base64

[JanSchankin]

Jackson saves byte[] in base64 format. According to Stackoverflow this might have been done to save space on disk. But in our case we often want to compare the byte[] in our .json to a byte[] in the debugger. This is e.g. the case if a byte[] parameter has changed so that a Sample is not found anymore.

So we should provide a custom serializer/deserialzer for Jackson that encodes byte[] in a readable form. This serializer/desrialzer should be default.
