IBAN validator and parser: Possibility to add multiple IBANs

[n-albrecht]

Checking multiple IBANs might occasionally be useful (e.g. I'm volunteering at a non-profit and one of my tasks is to enter donor info, IT tools helps me to validate the IBANs - among other uses)
Implementing the validation of multiple items itself is probably not a major issue (I assume it's adding a loop). Output will probably need to be redesigned, maybe in form of a table. Unfortunately, I only know a medium level of Python, so I will likely not be able to contribute unless someone guides me.
Thanks in advance if that will be implemented, if not, I'm still happy with the software, so thanks in general as well!
