Support feature to ignore fields with arguments

[tpdewolf]

Hi Dries,

Thanks for the work on this project. It works like a charm in combination with MikroORM!

I was having some issues where I wanted to ignore fields that have arguments because I don't want to query the entire relation, but only a subset. I've added the functionality to ignore fields when they have arguments. By default it's disabled so it shouldn't affect current functionality.
