Description

Hi there,

I would like to read Samsung specific tag from the attached photo captured by Samsung Galaxy S8 smartphone. The issue that ExifTool is able to read them and shows as:

But when I call getDirectories() then I could not find that Samsung directory, therefore I am not able to read all those tags.

Please guide me how to solve my issue if that's possible.

Research direction
Investigate Samsung MakerNote tags from the ExifTool output shown in the issue. Look at existing directory implementations in metadata extractor (e.g., for other camera brands) to understand the pattern. The Samsung tag IDs and types need to be mapped and a new SamsungDirectory class created. Check the metadata extractor documentation and existing tests for guidance.
