[Enhancement] Automatically reconnect after waking up from sleep.

[vinliao]

Is your feature request related to a problem? Please describe.
I noticed that my laptop's internet doesn't work after I woke it up from sleep, even though the internet works on other device. When I ran protonvpn status, it told me to run protonvpn reconnect.

Describe the solution you'd like
It would be nice to have it automatically reconnect every time it wakes up from sleep.

Describe alternatives you've considered
Another alternative solution for this problem is by creating a script to automatically reconnect in rc.local.
