Accommodate mirror and prism vertical flip
I have a small right angle prism attached to back camera which flips image vertically. I use portrait orientation. The camera is used for StarSense and I can't easily remove prism. Much easier to port to other scopes. Anyway some changes to code to allow image to be flipped vertically so your plate solving can actually recognize the image coming from camera in this orientation. This also means my phone is facing downward when camera sees horizon. Note this is different from the request for.digiscoping. Net result is same, but your app won't work with my setup at all unless it can flip the collected image vertically for those using a mirror or prism
