banking's Issues

Fails to validate some DK iban

DK0206715394960066 iban is considered invalid. Error I receive is: incorrect checksum: validation error

package main

import (
	"fmt"
	"log"

	"github.com/jacoelho/banking/iban"
)

func main() {
	err := iban.Validate("DK0206715394960066")
	if err != nil {
		log.Fatal(err)
	} else {
		fmt.Println("valid!")
	}
}

For example:
https://bank.codes/iban/validate/ or https://github.com/jbub/banking considers it valid.

Library version: v1.1.37 (latest as of now)

Bonus: during testing of this lib I found that from 350k unique ibans 3500 were falsely invalid.
