feat: add Duke Nukem Forever 2001 support

[podrivo]

Adds support for Duke Nukem Forever 2001.
Thanks @cetteup for testing and pointing the protocol! See more at #298

I'm not 100% sure about and could use a confirmation:

release_year: 2022, 
port: 7777, 
port_query_offset: 1

Example response:

node bin/gamedig --type dnf2001 45.89.125.89 --pretty

Thanks.
How did you found that server? When I first tried to add support for it I couldn't find any servers at all.
Querying it works as expected, but I'm saying this in the sense to really know if its a Duke Nukem Forever 2001 server, I had this problem with #446, I was querying a game server on it an apparently another server responded to the query and I caught that just before wanting to merge it.

[podrivo]

It was suggested on the issue by @cetteup. I haven't found any online server as well.
You get "gamename": "dnf" on the response, but not sure if it's enough to say it's the same game.

[CosminPerRam]

Well, that could be DNF 2011.

[podrivo]

I see. I'll check over their Discord to have confirmation and I'll update here in case they reply.

[podrivo]

Never got a reply from the admin EduCatOR about the server being DNF 2001 or 2011.
I wasn't able to find more information about it, nor other servers to test a bit more.

[CosminPerRam]

Over #298 they confirmed its DNF 2001 and not 2011, good to merge, just to rebase (:

[podrivo]

Rebased. Good to merge! (:
