RIFF::Info::Tag::properties() passed the result of the failed property key lookup, an empty string, to addUnsupportedData() instead of the field ID. An INFO chunk with a field that has no property mapping therefore reported an empty entry in unsupportedData(), and passing that list to removeUnsupportedProperties(), which erases by ID, removed nothing. Report the field ID instead, decoded as Latin-1 to match how removeUnsupportedProperties() encodes it. The new test sets a mapped field (INAM) and an unmapped one (ITRK), checks that unsupportedData() is ["ITRK"], and that removeUnsupportedProperties() with that list removes ITRK and keeps INAM.
