batches: un-optimize and move loading spinner SVG
Created by: courier-new
svgo
seems to break the animation on this loading spinner SVG, so I've reverted the optimization and stuck it in an unoptimized
folder to keep it separate from the rest and not fail the check.

From a cursory look over svgo
's issues, there are many other reports of svgo
breaking an animated SVG in some way or another, so I don't think it's worth trying to fix it in this case. The difference the optimization makes is minimal (only 32kb down to 30kb, or 7% reduction), and this SVG is only used within Batch Changes.
