Invalid date is accepted as valid kennitala

[MiniGod]

The isPerson validation does not account for invalid dates. I see the current code simply checks that the day is <= 31, but 310222 for instance is not a valid date, and hence not a valid kennitala.

Would have to parse the date and validate it.

One way to do it:

const isValid = isNaN(new Date('2022-02-31').getTime())

Interesting. Not a bad idea to validate the months.

This has been implemented on the v2 branch, you can try yarn add kennitala@2.0.0-beta.0 to test it out.

Available in V2.0.2 now non-beta.
