+替換權重：
+    1. 找到 async_infer_advanced_example.cpp 裡的 main ，將 hef 檔案替換成 YOLOv5 和 YOLOv7，如下
+    2. auto infer_model = vdevice->create_infer_model("yolov7_yuv21.hef").expect("Failed to create infer model");
+    3. 到 build 底下重新編譯 .\detection_app.exe
+
+
+目前輸入格式為 (YUV 大小會從 640 * 360 -> 640 * 640)：
+    .\detection_app.exe .\input.yuv output.yuv
