    d64ops: Mask out FLAG_HIDDEN from file type byte
    
    Mask out the unused 0x20 bit that is used as FLAG_HIDDEN internally
    when reading the file type from a directory. This bit is ignored by a
    1541, but if it was set in a disk image for some reason sd2iec would
    have hidden the file even though it should not.
