Using unbound-anchor for non-default trust anchor

[Edward Lewis via Unbound-users]

unbound-anchor, by default, pulls DNSSEC trust anchors from data.iana.org.

I am trying to test RFC 5011 capabilities by following these websites:

http://keyroll.systems
and
http://icksk.dnssek.info/fauxroot.html

Goal is to run unbound-anchor as a first step before trying to tune
unbound to either of those experiments.
