File upload

The ZeroQL supports file uploading via the "official" GraphQL way - the Upload type. There is an example:

public record AddAvatar(int Id, Upload File) : GraphQL<Mutation, int>
{
    public override int Execute(Mutation mutation)
        => mutation.AddUserProfileImage(Id, File);
}

There is one nuance associated with the Upload type. Pay attention to how you pass the Upload instance. For example, if it is a anonymous type new { File = new Upload("image.png", new MemoryStream()) } that means that reflection is going to be utilized to get the value. As a result, the Reflection.Emit is involved, which can be an issue in AOT scenarios. So, the "request" syntax would be better for such a case.
