feat(camera): wide zoom cameras in custom camera

[tsinis]

Hey again @longitachi, thanks for reviewing my previous PRs, here is another one.

This PR introduces a new feature to the ZLCustomCamera that allows users to utilize wide cameras (e.g., .builtInTripleCamera, .builtInDualWideCamera, .builtInDualCamera). This enhancement is designed to improve the flexibility and functionality of the camera, especially for users who need to capture wider shots. And it's also a feature that exists in the original UIImagePickerController but is missing in ZLCustomCamera.

Key Changes

• Added a new boolean property enableWideCameras to ZLCameraConfiguration.

• Updated the getCamera method in ZLCustomCamera to include the cameraConfig.enableWideCameras flag check along with the #available check.

• Modified the setInitialZoomFactor method in ZLCustomCamera to use an early return with the guard statement if cameraConfig.enableWideCameras is false.

• Enhanced the setVideoZoomFactor method in ZLCustomCamera to use the new implementation only if cameraConfig.enableWideCameras is true. Otherwise, it uses the original implementation.

Benefits

• Flexibility: This feature allows users to take advantage of wide cameras, providing more options for capturing photos and videos.

• User Experience: Users can now capture wider shots, which is especially useful for landscape photography, group photos, and more.

Non-Breaking Change

This change is non-breaking and does not affect existing functionality. The wide camera feature is disabled by default and can be enabled by setting the enableWideCameras parameter to true.

Please review the changes and let me know if there are any adjustments or additional features you would like to include. Thank you!

@available(iOS 11.0, *)
open var minAvailableVideoZoomFactor: CGFloat { get }

The minAvailableVideoZoomFactor property supports iOS 11 at the minimum, and an error will be reported when running here.

I noticed that when you used enableWideCameras, there were several places where @available(iOS 13.0, *) was judged, so I think it would be better to mark the enableWideCameras property as @available(iOS 13.0, *), what do you think?

Hey @longitachi, yes, it makes sense, I wanted this PR to have as few LOC changes as possible since an explicit availability check will still be needed for AVCaptureDevice.DeviceType. I provided changes, thanks!
