Add support for custom Faker providers in AnonymizedFaker and PsuedoAnonymizedFaker

[srinify]

Problem Description

Faker supports custom providers, which can be helpful for creating dummy data that's highly specific to someone's use case: https://faker.readthedocs.io/en/master/#how-to-create-a-provider

Extending AnonymizedFaker and PsuedoAnonymizedFaker to support this functionality would help increase the usefulness of RDT.

Hello, any update on this ? I'm highly interested in this feature :) our team is trying to use custom Faker provider with RDT :) for now the workaround we found is to monkey patch "is_faker_function" function but I don't like this.

Hello,
Me too !
Looking forward for some updates here :)
For now, I'm patching the rdt.transformers.pii.anonymization.is_faker_function()
Thanks
