Extend 'Raw JSON' report types to render processed json and YML trees

[nielsdejong]

Is your feature request related to a problem? Please describe.
Currently the Raw JSON report type returns the direct output from the Neo4j driver:

[
  {
    "keys": [
      "X",
      "Y"
    ],
    "length": 2,
    "_fields": [
      "A",
      {
        "low": 123,
        "high": 0
      }
    ],
    "_fieldLookup": {
      "X": 0,
      "Y": 1
    }
  }
]

It will be useful to also render a clean, processed JSON structure (with the _fields and _fieldLookup keys merged) to be more human-readable.

Describe the solution you'd like
For the example above, we can create an advanced report setting returnFormat with three settings ['raw', 'json', 'yml'] that determines the output.

Example for json for the data above:

{
  "X": "ABC",
  "Y": 123
}

Example for yml for the data above:

X: ABC
Y: 123

Additional format suggestion: xml - rendering the processed JSON as an XML tree.
