[dsc] Smart second-level-domain mapping

[Jerry Lundström]

Hi all,

This smarter PSL/TLD mapping feature is now available for testing thanks
to funding from NIC.AT!

  <https://github.com/DNS-OARC/dsc/pull/259>

If anyone wanna test this then please let me know and I'll send you
instructions how to set it up.

Cheers,
Jerry

For example using the https://publicsuffix.org/list/public_suffix_list.dat list?
