Updating Snapshots

If the images aren't equal, the test fails and OSnap puts the new image into a new __updated__ folder inside of your snapshot folder.

It also generates a new image inside of a __diff__ folder, which shows the base image (how it looked before), an image with the differing pixels highlighted and the new image side by side.

There is no "update" command to update the snapshots.
If the changes shown in the diff image are expected, you just have to move and replace the image from the __updated__ folder into the __base_images__ folder.
