Subject: Reduce maximum recursion depth in exif_data_load_data_content
Origin: https://github.com/libexif/libexif/commit/5d28011c40ec86cf52cffad541093d37c263898a

This only needs to be a small, single digit integer for normal files,
and reducing the maximum closer to this reduces the time and space
needed to detect pathological cases.
