Support iMessage Extension & Sticker Pack icons

[eralpkaraduman]

Let's support icon sizes for iMessage iMessage extensions & sticker packs.

Guidelines

Discussed under iMessage App and Sticker Pack Icons https://developer.apple.com/ios/human-interface-guidelines/extensions/messaging/

By the time I'm writing this, it required variations in sizes:

• 1024px by 768px
• 120px by 90px
• 64px by 48px
• 180px by 135px
• 96px by 72px
• 58px by 58px
• 148px by 110px
• 87px by 87px
• 54px by 40px
• 134px by 100px
• 81px by 60px

@jondot I'd be happy to implement this, do you have any notes?

I tried this Bladefile entry

- source: assets/icon-1024x1024.png
   mount: StickerPackExtension/Stickers.xcstickers/iMessage App Icon.stickersiconset
   contents: false

It created images in correct sizes but,

• It scaled them by distorting, tried to fit the frame, didn't clip ( iMessage icons are narrower in height ) I think clipping would be expected by most users
• Didn't assign the images. Generated images remain unassigned in .stickericonset folder in XCode

In the ideal future implementation: How clipping mode should be set in Bladefile? Or should there be a flag that stating this is imessage extension icon?
