Trying to open a zip file created with java's zip api and zip64 format leads to an exception.

This is because java zip api only writes entries in zip64 headers whose values are greater than max int value, and does not fill all the fields of the zip64 headers. For example, if the offsetLocalFileHeader is greater than max int value, but the file sizes are less than max int value, java zip api only write offsetLocalFileHeader in the zip64 headers. zip4j header reading has to be adjusted accordingly.
