Bug with CreditCardExpirationDateFormatter

[alfredo-handcash]

Hi! First of all, thanks for your time creating this package! Is amazing.

I found a bug from the 2.5.1 version in the CreditCardExpirationDateFormatter when you try to enter a January month, in this video you can see an example.

I think is related with this change: https://github.com/caseyryan/flutter_multi_formatter/blob/master/lib/formatters/credit_card_expiration_input_formatter.dart#L76

Thanks for your time!

Thanks again for your report. It was a really critical issue. Fixed in 2.7.5
