One Click Download all PNG 

A button on the readme page to download all pngs icons.
I think the default size will be 512 px.

I'm not sure why various kits will have sizes like 32, 64, 128, 256px variants.

If there is reason I am open to doing this.

The previous architectural icon kit has a bash file to covert svg to png.
I'm going to give it a look.
