1024x1024 and SVG icons for Franz

[gabrielkrell]

Hi! I'm working on a recipe to add Kiwi to Franz. To accept my plugin they'll need a larger icon:

In order to show every service icon crystal clear within the Franz UI, we require a .svg and .png in 1024x1024px.

I'd love to get the Franz people to include Kiwi, but doubt they'll accept my PR without icons that fit their spec. Does anyone (@xnite?) have access to larger source images than the ones in the icon folder here?
