Feature: Add "bzyd" White Noise Night Light

[ollief87]

Added support for the Tuya White Noise Night Light.

Note: the device has an RGB light with H/S/V values, but the "colour_data" property in the schema comes through as an empty object, so it required setting some defaults.

This is the device schema - note the empty object for "colour_data":

"schema": [
      {
        "code": "colour_data",
        "mode": "rw",
        "type": "String",
        "property": {}
      },
      {
        "code": "countdown",
        "mode": "rw",
        "type": "Integer",
        "property": {
          "unit": "min",
          "min": 0,
          "max": 1440,
          "scale": 0,
          "step": 1
        }
      },
      {
        "code": "status",
        "mode": "ro",
        "type": "Enum",
        "property": {
          "range": [
            "manual",
            "wake_up_1",
            "wake_up_2",
            "wake_up_3",
            "wake_up_4",
            "sleep_1",
            "sleep_2",
            "sleep_3",
            "sleep_4"
          ]
        }
      },
      {
        "code": "stop",
        "mode": "rw",
        "type": "Boolean",
        "property": {}
      },
      {
        "code": "switch",
        "mode": "rw",
        "type": "Boolean",
        "property": {}
      },
      {
        "code": "switch_led",
        "mode": "rw",
        "type": "Boolean",
        "property": {}
      },
      {
        "code": "switch_music",
        "mode": "rw",
        "type": "Boolean",
        "property": {}
      },
      {
        "code": "volume_set",
        "mode": "rw",
        "type": "Integer",
        "property": {
          "unit": "",
          "min": 0,
          "max": 100,
          "scale": 0,
          "step": 1
        }
      },
      {
        "code": "work_mode",
        "mode": "rw",
        "type": "Enum",
        "property": {
          "range": [
            "scene",
            "customize_scene",
            "colour"
          ]
        }
      }
    ]

The values reported for "stop", "switch" & "work_mode" never change no matter what I do with the device's physical buttons, or using the native Tuya mobile app. Here are example values from my device:

"status": [
      {
        "code": "colour_data",
        "value": "{\"h\":45,\"s\":1000,\"v\":270}"
      },
      {
        "code": "countdown",
        "value": 0
      },
      {
        "code": "status",
        "value": "manual"
      },
      {
        "code": "stop",
        "value": false
      },
      {
        "code": "switch",
        "value": false
      },
      {
        "code": "switch_led",
        "value": true
      },
      {
        "code": "switch_music",
        "value": true
      },
      {
        "code": "volume_set",
        "value": 33
      },
      {
        "code": "work_mode",
        "value": "scene"
      }
    ]
