feat: added WrapperPlayClientCraftRecipeRequest and WrapperPlayServerCraftRecipeResponse wrapper classes

With this pull request users can use two new wrappers that work fine - I think there is nothing more to explain.
It was tested with the server versions: 1.8.8, 1.12.2, 1.13, 1.13.2, 1.14.4, 1.15.2, 1.16.5 and 1.18.2
Client-Versions: 1.18.2, 1.16.5, 1.13
