Jaesung Chung 4118ca8627 ExifInterface: keep tags in the original tag groups
Previously ExifInterface saved its tags in the all possible IFD tags via
setAttribute() method even it already knew the right IFD group for those
tags. In this CL, it introduces updateAttribute() and removeAttribute()
methods in order to maintain the internal IFD tags and its values
according to its original EXIF saving states in the given JPEG file.
