Higher resolution image

- Takes images at highest possible resolution of camera
- Saves images using a background queue that will continue to work if the app is backgrounded
- Uses a screen sized preview image to give faster feedback to the user before saving the image
- Fixes the volume button trigger
- Saves the automatically created exif data from the photo

Note: since images are saved at a higher resolution than before it may take longer before they are fully processed and saved to the user's photo library on older devices.

Note2: Highest res images may be at a different aspect ratio than the previous ones and may need to be cropped if Noirca is supposed to only save at a specific aspect ratio.
