Natively support HEIC MacOS wallpapers

[Th3Dandy]

Hi,
Could we get HEIC file supports ? https://dynamicwallpaper.club/ has a bunch of of good wallpapers but can't be used easily on Windows. You can use the .HEIC to .DDW converter (https://ddw-theme-creator.vercel.app/) but it has 4 sets of images instead, when a lot of wallpapers have much more.

Thanks.
