Allow square/uncropped icons

[denilsonsa]

The current behavior displays all icons as circles.

I wish I could use plain square/uncropped images as icons, as I already has a small collection of such images. This will also be good as it is easier to recognize different shapes, and because it is easier to find/import square-ish images from anywhere else.

As a workaround for now, I can try to find new icons from https://github.com/krisu5/aegis-icons

This would make a hugh difference in the aesthetics of the app. Please.

We'll consider implementing this feature request while working on #509.

I would also like to use square icons.

I really like how FreeOTP looks on Android. But it lacks backup. So I am looking for an alternative.

Also interested in this feature, especially if you bought icon packs on Google Play and it doesn't show it right for the icons on Aegis
