There're tuples containing hobbies for every student in a class, e.g. hobbies_Adam = ('reading', ('jogging', 'boxing', 'yoga'), 'movies').
As you can see, some of the hobbies can be grouped in a nested tuple. Write a function that takes a tuple with student's hobbies and returns another tuple that contains all items of the original one, but "unpacked", e.g. ('reading', 'jogging', 'boxing', 'yoga', 'movies') for the example above. The depth of nested tuples can only be one, as in the example; there will be no input tuples like (hobby1, (hobby2, (hobby3, hobby4))).
