Broken link in readme

[MartinCapraro]

The link to the ZEAL package in the readme (http://cpc.cs.qub.ac.uk/summaries/ADKW) is currently returning a 404. Some quick googling did not help, and it looks like the internet archive last had a successful archive in 2007.

Thanks for spotting this! I've found https://elsevier.digitalcommonsdata.com/datasets/yc9vv7rwyj/1 which still seems to work so I will change the link to that
