Register new media transformations automatically

[wd60622]

Description

Adstock and Saturation Transformations will be registry automatically when the class is created (not instantiated). This will allow for a more seamless experience when using the transformations in the future.

from pymc_marketing.mmm import SaturationTransformation

# This registers the class with other saturation transformations
class Identity(SaturationTransformation):
    lookup_name: str = "identity"

    def function(self, x): 
        return x

    default_priors = {}

That makes the class available for serialization and deserialization (i.e. what is done in MMM load method)

from pymc_marketing.deserialize import deserialize

data = {"lookup_name": "identity"}
saturation_transformation = deserialize(data)

assert isinstance(saturation_transformation, Identity)
