Select key in a JSON structure and from that create a new JSON

Will only select the first occurrence of the key

For example from the JSON:

.. code-block:: python

    {
        "version":"1.0",
        "software":"sfd",
        "items" : {
            "a":"1",
            "b":"2",
             "c":"3"
        }
    }

we can select the key ``"items"``, which will produce the new JSON

.. code-block:: python

    {
        "a":"1",
        "b":"2",
        "c":"3"
    }
