Changing JSON array with circe at scala : I have a JSON string with array as the following:   

    {
    "cars": {
        "Nissan": [
            {"model":"Sentra", "doors":4},
            {"model":"Maxima", "doors":4},
        ],
        "Ford": [
            {"model":"Taurus", "doors":4},
            {"model":"Escort", "doors":2}
        ]
    }
    }
I would like to edit a new card brand, using ***circe*** at scala.  
Instead of 
  

    "Nissan": [
            {"model":"Sentra", "doors":4},
            {"model":"Maxima", "doors":4},
        ]

I would like to have as a result:

    "Nissan": [
            {"model":"Sentra", "doors":1000},
        ],
Thanks.
