Not an issue as such but a feature add #50
Description
Firstly this project has been a life saver for me so thank you.
My issue has been and this could be because of my shady Angular experience but when defining slots on my implementation a call is made for all adverts even those out of view which has caused issue for my client and they asked me to disableInitialLoad(), I think this would be a handy feature to add to the project I have manually added it to the copy that I have googletag.pubads().disableInitialLoad(); and it seems to work but others may benefit from this too.
Thanks again.
