Log:
IMAGING-172: Microsoft tags are not seen in MS Windows Properties/Details dialog
Null-terminate the XpString tag, and store it in the root directory where
Windows looks for it instead of the EXIF directory. Also deletes the
IPTC and XMP metadata which contains conflicting tags which Windows
uses instead when present.
