Fixed an issue where playback time was incorrect when video was taken.

i3DMovieCam uses two side-by-side cameras with different focal lengths on the back of the camera to take synchronized videos.
The conventional three-lens iPhone had a standard and a telephoto camera side by side, but the iPhone15 Pro has a new camera layout with a standard and an ultra-wide-angle camera side by side. To accommodate this change, a "Switch to standard and ultra-wide-angle cameras" option was added to the app settings.

Added pinch zoom function.
Recording can be aborted by tapping any button other than the record button while recording.
Preview stereo format can now be saved.

For iPhone 12 Pro Max only, change the default settings from 2.0 to 2.5 for "Zoom Ratio" and from OFF to ON for "Swap Camera Position".

Fixed a problem where the zoom function to adjust the left and right magnification does not work immediately after the application is launched.
