Add Battery level sensor readout for satisfyer devices

[MaxMustermann31]

All satisfyer devices I tested expose a default bluetooth battery level service on 0000180f-0000-1000-8000-00805f9b34fb.

Adding

          {
            "feature-type": "Battery",
            "description": "Battery Level",
            "sensor": {
              "value-range": [
                [
                  0,
                  100
                ]
              ],
              "messages": [
                "SensorReadCmd"
              ]
            }
          }

to the features section (or for devices with more than one vibrator, to the respective override section) and

              "0000180f-0000-1000-8000-00805f9b34fb": {
                "rxblebattery": "00002a19-0000-1000-8000-00805f9b34fb"
              },

to the services section of the device configuration json worked fine to get the battery level readout working,

Oh nice! I'll assign this over to @blackspherefollower since they have more test devices than I do.
