PIIAnonymizer not generating multiple locales

[pvk-developer]

Environment Details

• RDT version: v1.0.0.dev
• Python version: 3.7
• Operating System: PopOS! 20.04

Error Description

The current PIIAnonymizer does not work properly with the multiple locales passed. When we store the function provided by the user, we do not store the proxy function but the result of this, which leads to have a static generator instead of multiple one.

Steps to reproduce

import pandas as pd

from rdt.transformers import PIIAnonymizer

data = pd.DataFrame({'my_row': np.arange(0, 100)})
piia = PIIAnonymizer(provider_name='job', function_name='job', locales=['ar_AA', 'en_US'])

transformed = piia.fit_transform(data, 'my_row')
reverse_transformed = piia.reverse_transform(transformed)

The reverse_transformed object is expected to contain both Arabic and English job titles, but this will be random and only contain one of them (only English or only Arabic).
