Unity Vuforia 动态生成识别图，返回识别图的监听

* 1.下载 XML Dat 文件到本地 （XML Dat 的路径和文件名要一样）

* 3.生成完毕后 会返回识别图的监听 IEnumerable<ObserverBehaviour>
* 4.绑定监听 ObserverBehaviour

在相机上可以动态添加
OpenXRCamera.Instance.head.gameObject.AddComponent<VuforiaBehaviour>();
OpenXRCamera.Instance.head.gameObject.AddComponent<DefaultInitializationErrorHandler>();
目前的缺点：
二次加载识别图的时候，已经加载过的识别图监听会返回报错，需要自己维护一个表 做判断， 如果有重复的话不要删除当前的监听物体，卸载掉原监听事件，新增新的监听事件（目前还是理论，没有实际测过）
