Also, in the `Inputs` sub-directory, you'll find sample XRay traces of the old versions. It would be great if you can add version 3 sample binary traces there and add more tests to ensure that we are getting the expected data from the tools handling the newer version(s) of the traces.

I realise that I may have been a little unclear here.

To be clear, the suggestion is to create a binary that's XRay-instrumented and get version 3 files generated from those (for FDR mode). We don't need to keep the binary in the `Inputs` directory, we just need the trace file generated from this binary.
