Implement CPFValueObject as util Value Object

[4lessandrodev]

CPF stands for Cadastro de Pessoas Físicas (Natural Persons Register). Native Brazilians can request a CPF at any time in their lives - parents will often apply on behalf of their children when they are newborns, as CPFs are vital to living in Brazil and it’s best to obtain one sooner rather than later.

A CPF is 11 digits long, comprised of nine base digits, and two digits at the end that are the result of an arithmetic operation on the first nine numbers, meaning any typing mistakes will lead to an invalid number. Here is an example of a CPF: 231.002.999-00.
