Cross-vendor public domain suffix database in DAFSA form

The Public Suffix List is a cross-vendor initiative to provide an accurate list of domain name suffixes, maintained by the hard work of Mozilla volunteers and by submissions from registries. Software using the Public Suffix List will be able to determine where cookies may and may not be set, protecting the user from being tracked across sites. This package includes a DAFSA representation of the Public Suffix List for runtime loading.
