Elytra App Icon - Revision 3

This is the final form of the new Elytra App Icon. I'll be using the same across macOS, iOS and iPadOS conforming to their respective boxes (if any, nothing on macOS Catalina).

Compared to the previous revision, I removed all bitmap assets from the file so the icon is now purely vector. It renders very well in SVG as well (although not so well in certain contexts due to lack of support for things like blurring and blend modes).

I might still tweak the 64pt icon a bit more, reduce some details so that the base form is more visible and easily identifiable.

Let me know what y'all think of it, please feel free to share recommendations and suggestions to improve it.
