Support push notification via EU server

[letam]

Thanks for the helpful tool.

Please update to offer CLI option to specify EU API (api-eu.customer.io) when sending push notification.
(I was able to download project and manually change the endpoint to get it to work, and don't have time to fork and offer patch atm)
