Added heuristics for partial fix of #1525770: Microsoft Windows Photo Gallery 6.0.6000.16386 apparently converts main Exif IFD from Intel to Motorola order, but copies Olympus makernote in Intel order as-is. We now detect this order-mismatch, plus we now write back some unknown short in the makernote that seems to be version number.
