Consider embed jwt.RegisteredClaims to SubscriptionNotificationV2DecodedPayload?

[laeo]

I want parse SubscriptionNotificationV2.SignedPayload.SignedPayload payload to SubscriptionNotificationV2DecodedPayload by calls jwt.ParseWithClaims, but the struct does not fit jwt.Claims interface.

One option could be as below https://github.com/awa/go-iap#parse-notification-from-app-store

	token := jwt.Token{}
	client := appstore.New()
	err := client.ParseNotificationV2(tokenStr, &token)

	claims, ok := token.Claims.(jwt.MapClaims)
	for key, val := range claims {
		fmt.Printf("Key: %v, value: %v\n", key, val) 
	}

@laeo Another option could be to wrap SubscriptionNotificationV2DecodedPayload with jwt.RegisteredClaims, then jwt.ParseWithClaims could be called directly.

	type CustomClaims struct {
		jwt.RegisteredClaims
		SubscriptionNotificationV2DecodedPayload
	}
	ret := &CustomClaims{}
	t, e := jwt.ParseWithClaims(tokenStr, ret, func(token *jwt.Token) (interface{}, error) {
		return cert.ExtractPublicKeyFromToken(tokenStr)
	})

Thanks.
