Rework the way diagnostic events are serialized to JSON, and deserialized:
- add a "type" field to distinguish between live and freeze frame data;
- make a DiagnosticJson class to contain the deserialized JSON;
- move logic to make a VehiclePropValue out of JSON into its own class (DiagnosticJsonReader / DiagnosticJson.Builder)
This is useful/necessary because you need to know the number of vendor specific sensors if you're going to generate a valid
VehiclePropValue for a real vehicle instead of a test case
