Add Reference Field for Reporter

[lvfasto]

It would be helpful for reporting organisations to be able to enter an optional reference number (as a String) in the Reporter section of the JSON objects.
That way the receiving organisation can communicate with the reporting organisation easily/quickly.

To look something like this in an Abuse Report:
"ReporterInfo": { "ReporterOrg": "ExampleOrg", "ReporterOrgDomain": "example.com", "ReporterOrgEmail": "reports@example.com", "ReporterReference": "eg-1234" },

And something like this in the Schema
"ReporterReference": { "type": "string", "description": "reference number from the reporter" },

Hi,
I agree it would be useful, I will bring this up and we might include a field like this in the next version of xarf. Until then, feel free to further discuss this, in this issue.
