NFC: Saflok parser Date Rollover

[Arkwin]

Update the saflok parser to properly handle date rollovers.

Saflok plugin date rollover

• The Saflok parser now handles dates rolling over properly. For example, a car programmed with a creation date of 8/31/2024 and an interval of 2 days would say 8/33/2024 instead of 9/02/2024. This is now been corrected to properly display expiring dates.
