Resize Images: preserve EXIF tags and filename

This feature request is for extension: **firebase/storage-resize-images**

### What feature would you like to see?

I would like to have slightly more control over the thumbnail file generation through the extension's settings.
- optionally preserve EXIF tags from source in the output image (especially copyright)
- optionally disable the resolution suffix in filename (original_**200x200**.jpg) if only one thumbnail size is requested

### How would you use it?

When I have my extension configured to output images in the /thumbnails subfolder, I would like to tick two extra boxes to keep exif tags and filenames intact when generating the output into /thumbnails.
