Until now we always declared in the HPKG header that the package file is zlib compressed. For uncompressed files we would just store all individual chunks uncompressed. Now we handle completely uncompressed files slightly differently: We don't write the redundant chunk size table anymore. The size savings are minor, but it makes the uncompressed format read-streamable which may be handy.
