Wrong parameter order in BaseModelSerializer

[blackvvine]

Hi,

In the BaseModelSerializer definition, the Keras model is passed before the model ID:

mia/mia/serialization.py

Line 29 in d389d30

def save(self, model, model_id):

But in the ShadowModelBundle class the model ID is passed before the model object:

mia/mia/estimators.py

Line 118 in d389d30

self.serializer.save(ShadowModelBundle.MODEL_ID_FMT % i, shadow_model)

I think the BMS abstract class definition should be corrected with the two arguments swapped in order.

Best
