A2S_INFO requests a challenge

[Crizztl]

I noticed on many DayZ-Servers that A2S_INFO will require a challenge.
Currently, GetServerInfoAsync() will fail on those.

I think this is why my query against a valheim suddenly broke for me.
GetServerInfoAsync and the sync counterpart throws an exception using this example code

IServerQuery serverQuery = new ServerQuery(info.Ip, steamQueryPort);
var serverInfo = await serverQuery.GetServerInfoAsync().ConfigureAwait(false);

The serverQuery instance show its IsConnected flag as true.
I noted there is a implementation of requestChallange/RenewChallange, altho, i dont see a way to use them.

The actual exception:
System.NullReferenceException: Object reference not set to an instance of an object. at SteamQueryNet.Utils.DataResolutionUtils.ExtractData[TObject](TObject objectRef, Byte[] dataSource, String edfPropName, Boolean stripHeaders) at SteamQueryNet.ServerQuery.GetServerInfoAsync() at ... local stacktrace

GetPlayers call does not cause any exception tho

GetServerInfoAsync() uses SteamQueryNet.Utils.RequestHelpers.PrepareAS2_INFO_Request() which ignores challenges.
GetPlayers() uses PrepareAS2_GENERIC_Request() which works with challenges.

It has to be rewritten.
There's a Pull Request which includes this fix.
