What went wrong?

Delivery options do not load due to an error when creating the config. This occurs when a user enters a decimal value separated by a comma in the settings.

Reproduction steps

1. Enter 11,0 in a price field in the MyParcel carrier settings
2. Navigate to the checkout with a product in the shopping cart
3. Open the console and see the error in the network tab

Relevant log output

"Notice: A non well formed numeric value encountered in /var/www/magento2/app/code/MyParcelNL/Magento/Helper/Checkout.php on line 216"
