feat: more and improved resize options

[Bnyro]

closes #164

[SuhasDissa]

I have noticed a few issues with this,

• Applying the effects doesn't seem to do any visual change (for both portrait and landscape wallpapers)
• The app crashes when trying to process large images (especially from reddit)
• This PR doesn't fix the original issue

  When images are applied as wallpapers, the wallpaper should show the center of the image. However, all the resize options seems to set the top left part of the image as wallpaper.

The zoom option should center it, but there's still something wrong with it apparently.

The zoom option does center it.

It didnt work when I tested it

Oh, I see where it's crashing for some reason.

I've rewritten the zoom method from scratch, it does work well in my tests now.

This has been fixed with the previous commits.

I can't reproduce that, but I don't think that's caused by this PR.
