New datasets documentation

[slavkoja]

I found this repo more than year ago, i took look to README/manpage, but it shows nothing new, thus i leave it as another copy only. Then i meet your post into mailop ML, where you mention new features and i did another look, to know how to use them, but again nothing.

Please, document these new features, to one do not need to understand C to can use them.

In fact, this project needs a little more attention indeed. It has some very useful features, such as generic ipv4/ipv6 zones, fast hash zones, much faster networking etc. It is all not documented, there are no packages/docker images so it is hard to use. We need to fix it all.
