Struct zipios::anonymous_namespace{zipcentraldirectoryentry.cpp}::ZipCentralDirectoryEntryHeader: This structure is aligned on 4 bytes since it includes some uint32_t values and thus has a size of 48 bytes instead of 46.
Member zipios::BackBuffer::readChunk (ssize_t &read_pointer): We may want to throw an error if m_is.is_good() returns false.
Class zipios::VirtualSeeker: The class is not linked to an input stream when created or the offsets get modified. This means the seek and tell functions cannot be sure that the offsets are valid of the specified input buffer.
