AutoSDK图层模块支持业务图层优先级可配置，客户端需要定义一个json文件，包含图层优先级配置信息。在调用BizControlService.init初始化图层服务时传入json文件全路径文件名，由AutoSDK解析并设置各业务图层的优先级。
配置方法：
根据业务图层与底图的优先关系及"图层绘制层级优先级"表设置"draw_priority"的优先级值
根据图层与图层的优先关系，设置"sub_priority"的优先级值，值由客户端自定义，取值范围为：-32768~32767，数字大小决定优先级高低，数字越大优先级越高
如果有新的图层增加进来，在确定新图层优先级时，为了避免已有优先级的变更，取新图层优先级上下两个图层优先级的中间值。

1、图层类控制和图层名是固定的，请直接使用上面配置中的名称，只需要调整优先级值。
2、"draw_priority"使用LayerDrawPriority的各项值，"sub_priority"根据图层间的优先级来设置优先级值，建议两个图层的优先级相差一个比较大的数值，方便以后优先级调整时不会影响到其它图层的优先级。
3、自定义业务图层控制器优先级配置“custom_control”，根据BizCustomTypeXXX1和"xxx_custom_layer_1"配对，其它图层类似。比如BizCustomTypePoint1对应的图层名是“point_custom_layer_1”，BizCustomTypePoint2对应的图层名是“point_custom_layer_2”
4、自定义业务图层要从BizType为1开始使用，中间不能间断。因为读取自定义业务图层的优先级是循环从1开始，如果不是从1开始或者中间有间断，后面的自定义业务图层优先级就不会被读取到。
