No switch to Zip64 if the zip file gets larger than 4 GB

[sesom42]

If files are added to a Zip archive using the mz_zip_writer_add_file function and the 4 GB limit is exceeded, the system does not automatically switch to Zip64. The resulting zip archive is then defective.

There is already a test in the mz_zip_writer_add_mem_ex_v2 function, but it only tests whether the 4 GB limit is exceeded by adding the header. Whether this limit is exceeded after the subsequent writing of the compressed data is no longer tested.

I use code like this:

mz_bool success = true;
success &= mz_zip_reader_init_file(&zip, pZipFileName, 0);
success &= mz_zip_writer_init_from_reader(&zip, pZipFileName);
success &= mz_zip_writer_add_file(&zip, pAliasName, pFileName, "", 0, MZ_DEFAULT_COMPRESSION);
success &= mz_zip_writer_finalize_archive(&zip);
mz_zip_writer_end(&zip);

After mz_zip_writer_finalize_archive success is false, if archive gets larger than 4 GB and the zip archive is defective.
