Add single-line installation command

[Rafficer]

For usabilities sake. Maybe there's a more beautiful version than calling those commands one after another. Didn't work for me with wget -qO- ... and | bash -s -- -install

Also more beautiful would be to put those commands in an extra file, maybe even hosted on protonvpn.com and doing wget -qO- https://protonvpn.com/support/linuxinstall | bash

I just tested this. wget -qO- https://ncrypt.sh/linuxinstall_test | bash looks a lot more beautiful and works the same.

I also thought about adding echo "Initialize protonvpn-cli now with sudo protonvpn-cli -init" at the end of the installation function, to make it more clear, but wanted to hear thoughts on that first :)

HI @Rafficer

Thanks for the PR!

I will discuss the approach with the team, I would prefer using git so it's more clear to users.

Maybe we finish the next build, there is another installation method that are simpler.

We can use:

sudo bash -c "git clone https://github.com/ProtonVPN/protonvpn-cli.git ; ./protonvpn-cli/protonvpn-cli.sh -install"

In addition to the current one.

Sounds good to me :)

Maybe also consider to add wget -qO- https://ncrypt.sh/linuxinstall_test | bash (obviously on protonvpn.com) on the support page as alternative quick install.

Definitely we will have a simpler installation method in the future.
We have on long-term at #27
