I would return the first (or last - must be discussed) error of the
highest severity of all errors/warnings encountered.
Presently, the current code gives up parsing an IFD if an unknown tag
is encountered (unless in LIBMNOTE) which is not the case
when wrong tag format is encountered (via CF & CC macros).
Therefore EXIF_RESULT_UNKNOWN_TAG would be returned regardless
of the order.

The current code can encounter 2 non-100%OK codes
only if they are encountered in two different IFDs.
