A wrapper for Unbound in Go.
ub_result has been extended with an slice of dns.RRs, this alleviates
the need to parse
The website for Unbound is https://unbound.net/, were you can find further documentation.
Tested/compiled to work for versions: 1.4.19, 1.4.20, 1.4.21.
Note: using cgo means the executables will use shared libraries (for OpenSSL, ldns and libunbound).
