[BUG] Issue to configure Prophet

[ivan-marroquin]

Describe the bug
Thanks for such great package!

I am following the jupyter notebook 1_AnomalyFeatures. I get the following error when the Prophet model is configured:

TypeError: to_dict() missing 1 required positional argument: 'self'

To Reproduce
Just run the three first cells in the notebook

Expected behavior
Have the Prophet model configured without error

Screenshots

Cell In [35], line 32
28 # Prophet is a popular forecasting algorithm. Here, we specify that we would like
29 # to pre-processes the input time series by applying a difference transform,
30 # before running the model on it.
31 config3= ProphetDetectorConfig(transform= DifferenceTransform)
---> 32 model3= ProphetDetector(config3)

Hello, I was able to reproduce the error. In your case, note that the problem arises from incorrectly passing DifferenceTransform instead of DifferenceTransform() as the transform argument in ProphetDetectorConfig on line 31.
