The example in README should be updated

from

# print result as lists per output parameters
print(f'Stoch(5, 3) decomposed result: {stoch.to_lists()}') # {'k': [70.83333333333333, 50.0, 42.857142857142854], 'd': [None, None, 54.563492063492056]} 

to

# print result as lists per output parameters
print(f'Stoch(5, 3) decomposed result: {composite_to_lists(stoch)}') # {'k': [70.83333333333333, 50.0, 42.857142857142854], 'd': [None, None, 54.563492063492056]} 

with library imported on top

from talipp.indicator_util import composite_to_lists
