Description of the feature / 需求描述

HEIC images can be previewed in grid view, but cannot be displayed properly in image view. Therefore, it is expected that they can be displayed in image view like regular image files (such as PNG)

HEIC图片在网格视图下可以正常预览，然而在图片视图中无法正常显示，因而期望在图片视图下能够像一般图片文件（如PNG）一样展示

只有safari能支持(alist设置-预览里自己加上heic)，列表下缩略图是网盘转码生成的，并不是heic。
