Given a selector and a domain it'll slurp the record from DNS.

Then it parses it, using the BNF from the spec (<rhetorical>why, oh,
why do we support FWS in a DNS record?</rhetorical>) and then
sanity checks the various fields and gives a good / bad message.

If anyone has good (or known bad) records that it gets wrong I'm
interested to hear about it.
