Sending external sensors as nested JSON object

[3rwww1]

for instance we send the values of externel sensors in the string. example with a CSS811: ..."CO2":768,"VOCT":54,"temp":25... the configuration is :

"sensor0":
    {
        "reference":"Adafruit_CCS811",
        "type":"AirQuality",
        "address":90,
        "kind0":"CO2",
        "kind1":"TVOC",
        "kind2":"temp"
    }

what we want to get is the type as key for the nested array, like this: ..."AirQuality":{"CO2":768,"VOTC":54,"temp":25}...
