Naming collision with Oban.Pro.Decorator using `decorated` module attribute

[hogiyogi]

We are using both this library (which is great, thanks by the way!) and the Oban.Pro library but there is a naming collision among module attributes between these two for :decorated causing compilation errors since functions that are decorated using Oban.Pro are appearing in an unexpected format inside the Decorator code gen causing the following error:

** (FunctionClauseError) no function clause matching in anonymous fn/1 in Decorator.Decorate.decorated_functions/1    
    
    The following arguments were given to anonymous fn/1 in Decorator.Decorate.decorated_functions/1:
    
        # 1
        {:my_function, [{:args, [line: 254, column: 35], nil}], [], []}
