Fix share button

[john-rocky]

Fixed the share button functionality.
You can now share screenshots including camera footage.
With the existing code, the camera image part of the screenshot taken with the share button will be white. This is because AVPreviewLayer cannot be rendered as is.
The app was able to display the camera image by temporarily setting the camera image in imageview and inserting the imageview layer into videoPreview.

🌟 Summary

Enhanced photo sharing and capturing functionality in the YOLO iOS app. 📸✨

📊 Key Changes

• Simplified photo sharing: The process to share a photo has been streamlined by directly capturing photos using AVCapturePhotoSettings and the app's existing camera output, removing previous complex steps.
• Improved image processing: Added steps to display the captured image with the correct aspect ratio and orientation, then removing the temporary display layer once the image is ready to share.
• Code cleanup: Removed unused lines of code and comments related to the old method of taking screenshots and saving images, making the codebase cleaner and more maintainable.

🎯 Purpose & Impact

• Faster sharing: Users can now share photos faster and more efficiently, directly from their live camera feed, enhancing the overall user experience. 🚀
• Higher quality images: The updates ensure images are captured and shared with the correct orientation and aspect ratio, improving the visual quality of shared content. 🖼️
• Cleaner code: The changes contribute to a cleaner codebase, which is easier for developers to navigate and modify in the future. 👨‍💻👩‍💻
