Subject: [PATCH 1/2] Assume PSD2 is supported for any HITANS newer than v6

The logic was written when HITANSv6 was the newest version and also the only one that supported PSD2. Nowadays we have even newer versions and some banks support _only_ those (not anymore v6), so we need to be more lenient here.
