Add support to query ids returning arrays and objects

[HoLo85]

Added capability to store message arrays in custom messages.

hi, updated the PR. The returned array values look like this with the current implementation: {"dc_power":[2067,479],"dc_voltage":[58645,40779],"dc_current":[3527,1178],"available_sessions":2}

Had to do an update to the code so messages with objects also get stored if requested. The output will stay as it was, but now extended by array and object messages.

Input:

"sma_config": {
    "id": "1",
    "values": {
        "6100_0046E500": {
            "name": "phase1_voltage",
            "divider": 1
        },
        "6380_40251E00": {
            "name": "dc_power",
            "divider": 1
        },
        "6380_40451F00": {
            "name": "dc_voltage",
            "divider": 1
        },
        "6380_40452100": {
            "name": "dc_current",
            "divider": 1
        },
        "6180_00522900": {
            "name": "unknown",
            "divider": 1
        },
        "6180_08652500": {
            "name": "unknown2",
            "divider": 1
        }
    }
}

Output:

"phase1_voltage":23543,
"dc_power":[156,404],
"dc_voltage":[56146,33022],
"dc_current":[279,1226],
"unknown":{
    "low":0,
    "high":0,
    "val":null
},
"unknown2":{
    "tag":303
},
"available_sessions":1
