[Feature Request] Add support for viewing HEIC files.

[VioletStarkillr]

I use this program on my Windows desktop, and I have an iCloud sync from my iPhone onto my PC. Allusion works fine with the synced pictures, however It doesn't seem to display the HEIC photos taken from my iPhone. This would allow to me use Allusion to organize photos I take out in the world for use as reference, along with all my other references.

Apologies if this is not the right place to post this. I created a Github account just to make this request, I love the software so much, and this is the missing piece for my pipeline.
