conf generator syntax problem

there is strict string rule in https://github.com/amnezia-vpn/amnezia-client
which prevents using split tunneling function

because of `lack of \s` in conf, which generated through **this** great project

example:
in Amnezia expects `AllowedIPs = 0.0.0.0/0, ::/0`
this proj generates conf with `AllowedIPs = 0.0.0.0/0,::/0`

lack of space blocks split tunneling function in AmneziaVPN Client (i'v been tested this fact.)

soo i created [issue](https://github.com/amnezia-vpn/amnezia-client/issues/2206) in Amnezia proj about that. i think that this problem should be fixed on their side.
anyway it's only ur decision fix it here or not.
