Integrate SDK Setup

The API below is used for integration setup

   * Configure the SDK with the given options.
   *
   * @param options - The configuration options
   * @returns A `Promise` resolving with a `PassioStatus` indicating the current state of the SDK.
   */

  /**
   * Prompt the user for camera authorization if not already granted.
   * @remarks Your app's Info.plist must inclue an `NSCameraUsageDescription` value or this method will crash.
   * @returns A `Promise` resolving to `true` if authorization has been granted or `false` if not.
   */
  requestCameraAuthorization(): Promise<boolean>

/**
   * This method indicating downloading file status if model download from passio server.
   * @param callback - A callback to receive for downloading file lefts from queue.
   * @param callback - A callback to receive download file failed for some reason.
   * @returns A `Callback` that should be retained by the caller while downloading is running. Call `remove` on the callback to terminate listeners and relase from memory.
