Valetudo gen1 support

[pkishino]

Is your feature request related to a problem? Please describe.
when using this card with valetudo gen1, the attributes do not correctly show the data

Describe the solution you'd like
valetudo attributes such as mainBrush, sensor etc are named slightly different then in this card

Describe alternatives you've considered
I have manually updated the file locally to support valetudo naming, would need to use some good switch to know which device and hence which attribute naming to use

Additional context
here is example of my valetudo attributes:

{
    "mainBrush": "103.4",
    "sideBrush": "3.4",
    "filter": "103.6",
    "sensor": "28.7",
    "cleanTime": "196.2",
    "cleanArea": "11859.0",
    "cleanCount": 570,
    "last_run_stats": {
        "startTime": 1588800816000,
        "endTime": 1588801930000,
        "duration": 1114,
        "area": "15.0",
        "errorCode": 0,
        "errorDescription": "No error",
        "finishedFlag": true
    },
    "state": "docked",
    "valetudo_state": "CHARGING",
    "zoneStatus": ["bedroom"]
}
