Select image style of icon image

Great module!

I just miss you to choose which image style to use when you select icon mode in the field form.

Interesting idea, that could prevent huge images but I think I would prefer having a maximum width set via CSS instead of adding processing of those icons here. Also when we will support file paths to the icons which is easier with deployments we couldn't process them via image styles because they are not in the file system.
