Applicable scene:
Search all prefabs in the specified folder and find all referenced images and paths.
Step analysis:
1. Obtain the resource path through guid
2. Get the path containing the suffix .prefab in the folder
Load the resource (if you edit the resource, you need to add Start resource editing AssetDatabase.StartAssetEditing() before loading the resource and add End resource editing AssetDatabase.StopAssetEditing() after the operation is completed)
4. Traverse the prefab to find the object with the Image component on it, and obtain the path and image size information of iamge.sprite
5. Write this information locally to facilitate resource packaging and management

}Additional notes:
When editing resources, you need to note that UGUI inherits Graphic. If the UI that inherits Graphic is referenced by other UIs without using the editor, the reference will be lost, so we need to add one step when editing (remember the UI Quote, restore after editing is complete)
