[Franklin] So we created an image using the commands that Jake is using in his
script due to people still complaining that they can't create an SD Card on
Windows. We actually created a manual image as part of the SDK download page
for SDK 7.0. However, I am all for using an alternative solution if wic would
work. The reason why I never submitted similar patches was due to my dislike of
consuming system resources (loop devices) and all the required sudo commands.
