Added intermediate representation for DNS datasets

Browse source 
It's just CSV.
The DNS from the datasets are not ordered consistently,
so we need to parse it completly.
It seems that converting to an IR before sending data to ./feed_dns.py
through a pipe is faster than decoding the JSON in ./feed_dns.py.
This will also reduce the storage of the resolved subdomains by
about 15% (compressed).
