Update Tuya builder DP attribute_name type to match underlying DPToAttributeMapping class

[jeverley]

Proposed change

This amends the attribute_name argument type in tuya.builder methods tuya_dp and tuya_dp_attribute to support str and tuple to match the underlying DPToAttributeMapping class.

This is used in DPToAttributeMapping definitions to map a data point to multiple cluster attributes.

Additional information

Class that the attribute_name is used to populate:

@dataclasses.dataclass
class DPToAttributeMapping:
    """Container for datapoint to cluster attribute update mapping."""

    ep_attribute: str
    attribute_name: Union[str, tuple]
    converter: Optional[
        Callable[
            [
                Any,
            ],
            Any,
        ]
    ] = None
    endpoint_id: Optional[int] = None

This would be used in a v2 quirk as below:

    .tuya_dp(
        dp_id=6,
        ep_attribute=TuyaElectricalMeasurement.ep_attribute,
        attribute_name=(
            TuyaElectricalMeasurement.AttributeDefs.rms_voltage.name,
            TuyaElectricalMeasurement.AttributeDefs.rms_current.name,
            TuyaElectricalMeasurement.AttributeDefs.active_power.name,
        ),
        converter=lambda x: TuyaPowerPhase.variant_3(x),
    )



class TuyaPowerPhase:
    """Extract values from a Tuya power phase datapoint."""

    @staticmethod
    def variant_3(value) -> Tuple[t.uint_t, t.uint_t, int]:
        voltage = (value[0] << 8) | value[1]
        current = (value[2] << 16) | (value[3] << 8) | value[4]
        power = (value[5] << 16) | (value[6] << 8) | value[7]
        return voltage, current, power * 1
