Description

In Czechia we use often sms-sluzba.cz for sending SMS notifications and it would be nice to have it integrated within Symfony Notifier.

I could make a PR.

Documentation of SMS gateway is here (in Czech).

Example

# .env.local
SMSSLUZBA_DSN=sms-sluzba.cz://USERNAME:PASSWORD@default

...then use this texter as usual.
