Toggle to remove gen remaining from the HUD

I don't always want to see the number of generators remaining when playing killer.

Sometimes I want to chill and run after people with no care in the world about their objective and having a constant reminder on my HUD of how many gen remain makes it harder to do that.

You can already toggle the hook counter (the killer's objective), so why not allow us to do the same with the generator counter (the survivors' objective)?
