Setting generateThumbnail to true causes App to crash #280
Description
It appears as though the NextLevelPhotoConfiguration.avcaptureDictionary() function tries to add the kCVPixelBufferPixelFormatTypeKey if available in the __availablePreviewPhotoPixelFormatTypes, however it also adds the
AVVideoCodecKey, which causes a consuming app to crash with this callstack:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** +[AVCapturePhotoSettings photoSettingsWithFormat:] kCVPixelBufferPixelFormatTypeKey and AVVideoCodecKey may not both be specified'
*** First throw call stack:

libc++abi: terminating due to uncaught exception of type NSException
I'm guessing because those two keys are mutually exclusive according to the docs :)
This is on both iOS15 and iOS 17
I would also note that the NextLevel property of generateThumbnail is probably mis-named and should be generatePreview, given that Previews and Thumbnails are actually different things according to the docs here: https://developer.apple.com/documentation/avfoundation/avcapturephotosettings/1648696-previewphotoformat
