NPE for IBAN with country code

[manosbatsis]

Trying to get an IBAN using a country code provided by Faker itself results to a null pointer, e.g.

faker.finance().iban(faker.country().countryCode2())

Gives:

java.lang.NullPointerException: Cannot invoke "String.length()" because "str" is null

Versions:

• JDK Runtime Environment (build 17.0.8.1+1-Ubuntu-0ubuntu122.04)
• Faker Version 1.0.2

My suggestion would be to make Finance.countryCodeToBasicBankAccountNumberPattern public or add a method to access it's keys so they can be used for random selection of a country scope.
