Let the user specify the numero_afiliacao and chave_acesso in the initialize method. 

Hi,

I have a lot of numero_afiliacao and only one store (like a marketplace). I have to create a transaction with a different configuration each time. I changed the code to let me specify a numero_afiliacao and chave_acesso in transaction's initialize method but it is not mandatory. If this data is not informed it will work as expected before. I created a few tests and ran it. It seems to be working fine.
