Codify document options

[hsyed]

We just heard from Onfido that the document check can return address information if the document contained it (driving license). This need to enabled in options as follows:

{
	"type": "express",
	"asynchronous": true,
	"reports": [{
		"name": "document",
		"options": [
        {
          "name": "document_address_information"
        }
      ]
	}]
}

Since a lot of the fields are type-safe (ish) is there a nice way to encode this ? At the moment the options field is map[string]interface{}.

hmm, it should probably be []map[string]interface{} ?
