[PMT] Allow admins to rotate photos after uploading. (2 week ticket)

Overview

Allow users to rotate the orientation of photos they upload of the pet.

Add rotate buttons to the File preview component if the file is an image.
Install react-easy-crop for the rotating.
Look at this example for help. We want the user to rotate the image and then replace the original image in our array with the rotated one. Look at the removeFile() function for how the updating occurs.
We don't need any of the crop/zoom/other stuff, so if you find an easier way to rotate the image that also works
