Incorrect scheme for SmartHomeV1QueryResponse

[Shatungoo]

2 optional fields (errorCode and debugString) missed inside interface SmartHomeV1QueryResponse.

Scheme from google https://developers.google.com/assistant/smarthome/reference/intent/query#response_format payload:

• errorCode: String. Optional. An error code for the entire transaction—for auth failures and partner system unavailability. For individual device errors use the errorCode within the device object.
• debugString: String. Optional. Detailed error which will never be presented to users but may be logged or used during development.
• devices: Object. Map of devices. Each property has the following name and value:

Library(src/service/smarthome/api/v1.ts) doesn't contain errorCode and debugString into reposnce(it uses the same scheme as payload for SmartHomeV1QueryRequest)

export interface SmartHomeV1QueryPayload {
  devices: ApiClientObjectMap<any>
}

export interface SmartHomeV1QueryResponse {
  requestId: string,
  payload: SmartHomeV1QueryPayload
}
