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).
Rules can now come in 3 different formats:
- AdBlock rules
- Host lists
- Domains lists
All will be converted into domain lists and aggregated
(only AdBlock rules matching a whole domain will be kept).
Subdomains will now be matched if it is a subdomain of any domain of the
rule.
It is way faster (seconds rather than hours!) but less flexible
(although it shouldn't be a problem).
