Fix InputStream resource leak in ImageResizer.getOrientationMatrix()

Fix: Resource leak in ImageResizer.getOrientationMatrix()

Problem

The InputStream opened in getOrientationMatrix() was not being properly closed, causing a resource leak.
We discovered this when we turned on StrictMode on our Android app to trace memory related problems:

StrictMode policy violation: android.os.strictmode.LeakedClosableViolation: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks. (Ask Gemini)

Solution

Wrapped the InputStream in a try-with-resources statement to ensure automatic resource cleanup.

Changes

• Updated android/src/main/java/com/reactnativeimageresizer/ImageResizer.java line 322-324
• Changed from manual InputStream management to try-with-resources pattern

Impact

• Prevents resource leaks when reading image orientation metadata
• Follows Java best practices for resource management
• No functional changes to the API

Testing

• Existing functionality remains unchanged
• Resource cleanup is now guaranteed even if exceptions occur
