Fix EXIF handling of strings of four characters or fewer. #190

Closed ppelleti closed 3 years ago

The handling of short ExifString is analogous to the handling of short ExifUndefined. (See "Value Offset" in section 4.6.2 of EXIF Version 2.3 spec.)

This was causing trouble with tags like SubSecTimeOriginal (0x9291).
