Use rikudou/iban

[RikudouSage]

Instead of the bundled implementation, you could use the decoupled rikudou/iban and optionally provide an implementation of the interface for some local format.

Also you may move your Hungarian adapter from this package to the rikudou/iban package to make it available even in contexts outside QR payments.

Thanks, I've decoupled the IBAN interface (f792d27).

Concerning the Hungarian adapter, I have it prepared, but have to write some tests firsts (hopefully will pull-request it by end of the week).

Bundled implementation of the Hungarian IBAN adapter and validator successfully moved to rikudou/IBAN, thus closing the issue.
