Support keys larger > 1024 characters

Fixes #942
To use, new up the scanner and specify the overriden maximum key length, when deserializing use the scanner. Here is an example:

[Fact]
public void SupportRealyLongStrings()
{
    var longKey = string.Concat(Enumerable.Repeat("x", 1500));
    var yamlString = $"{longKey}: value";
    var scanner = new Scanner(new StringReader(yamlString), true, 1500);
    var parser = new Parser(scanner);
    var deserializer = new DeserializerBuilder().Build();
    var yaml = deserializer.Deserialize<Dictionary<string, object>>(parser);
    Assert.Equal(longKey, yaml.Keys.First());
}

Hey there, thanks so much for this change! Quick question because I might be missing something: Passing the scanner as argument to .Deserialize as shown in the snippet above causes a compiler error for me (.Deserialize only takes string, TextReader or IParser as arguments). I updated to 16.1.0.

I missed a line in my example. You have to new up a parser and pass that in. I’ll update the example shortly.

Updated.
