Gateway is not awailable for Torret Zasilkovna shipping method

Fastfix:

// wp-content/plugins/gopay-gateway/includes/class-gopay-gateway.php
$this->enable_shipping_methods      = array_merge(
     $this->get_option( 'enable_shipping_methods', array() ),
     array('zasilkovna>z-points')
);

Plugin Zasilkovna by Torret uses a different parameterization with which our GoPay for WooCommerce plugin does not work.
We recommend using the Packeta plugin: https://cs.www.ads-software.com/plugins/packeta/.
