Could you provide an API to get rotation #96

Hi, Thanks for bringing this great and simple to use library to the public. It would be really nice to have a way to know image orientation (and even better get exif metadata).

Thanks.

This is a good idea, not sure how we want to implement or if we want to take any dependencies on other libraries.

Right now the best workaround is to read the exif data using another library and then apply the rotation to the jpeg afterwards. When this library saves the image, it is saving exactly how the image is stored as heif, but it does not read any of the rotation exif data to get the orientation. This is the solution we use internally in our proprietary code as the goal of this library is to be as lightweight as possible
