Fixed the typo across 2 mixin files
Removing most of the icon classes in icon.scss, and the associated image assets. Still need to switch from the image to the SVG on 'PayingWithGoCardless' page.
Switched the white logo image for the SVG on 'paying through gocardless', and then deleted that image and icon.scss
