White spaces should not be considered when validating IBANs

[leobeal]

DE89370400440532013000 and DE89 3704 0044 0532 0130 00 should return the same result when validating IBANs.

Simply using iban.replaceAll("\\s+","") and always validating againg the version with no spaces solves the issue

@leobeal This was already a capability of the library since 2015. You can use org.iban4j.Iban#valueOf(java.lang.String, org.iban4j.IbanFormat). This will either return an Iban instance or throw an error is the iban is invalid.

 Iban.valueOf("DE89 3704 0044 0532 0130 00", IbanFormat.Default)

According to @leobeal comment, this is not the case
