Broken Link in README

[zachajon-cisco]

In the README, this link is broken:

Note that on Debian systems, binary packages of nmsg and its dependencies are available from a Debian package repository maintained by Farsight Security. These packages should be used in preference to building from source on Debian-based systems.

I propose changing to this link - https://www.domaintools.com/wp-content/uploads/DomainTools-SIE_User_Guide.pdf

Thanks for this report. I don't think the proposed link is equivalent, we will look for an updated link or remove the reference.
