Tuya sensor not display RAW values

[FredrikM97]

The problem

I attempt to fetch a RAW type data from Tuya https://developer.tuya.com/en/docs/iot/f?id=K9gf468bl11rj After local debug I can see that the data is found but the value from native_value returns None and therefor no data is set in the UI.

# Get subkey value from Json string.
        if self._type is DPType.JSON:
            if self.entity_description.subkey is None:
                return None
            values = ElectricityTypeData.from_json(value)
            return getattr(values, self.entity_description.subkey)

        if self._type is DPType.RAW:
            if self.entity_description.subkey is None:
                return None <---- enter here

If I set the subkey it will use the ElectricityTypeData which does not match my object (Example: "fwQAAgF/BgABAX8JAAEBfw8AAQF/FQACAX8XAAEBKBIAAQA=").

If I return value of no subkey is set does work and present the data I want. However it would be even better if a custom object similar to ElectricityTypeData could be added for decoding the data.

  if self.entity_description.subkey is None:
                return None

Is there any approach to allow other types than ElectricityTypeData and not be dependent on a subkey to return a value and instead take the raw value directly?
