add nordvpn prompt segment

Browse source 
This segment has four states.

MISSING: nordvpn is not installed. By default the segment is not shown
in this state. Override POWERLEVEL9K_NORDVPN_MISSING_CONTENT_EXPANSION
and/or POWERLEVEL9K_NORDVPN_MISSING_VISUAL_IDENTIFIER_EXPANSION to make
the segment visible.

CONNECTED: nordvpn is connected. By default shows LOCK_ICON as icon and
country code as content. In addition, the following variables are set
for the use by POWERLEVEL9K_NORDVPN_CONNECTED_CONTENT_EXPANSION
and POWERLEVEL9K_NORDVPN_CONNECTED_VISUAL_IDENTIFIER_EXPANSION:
P9K_NORDVPN_PROTOCOL, P9K_NORDVPN_IP_ADDRESS,
P9K_NORDVPN_SERVER, P9K_NORDVPN_COUNTRY, P9K_NORDVPN_CITY and
P9K_NORDVPN_STATUS (always "Connected"). These correspond to the output
lines of `nordvpn status`.

DISCONNECTED: nordvpn is disconnected. By default shows LOCK_ICON as
icon and FAIL_ICON as content. P9K_NORDVPN_STATUS is set to "Disconnected".

OTHER: nordvpn is in status other than "Connected" or "Disconnected".
I'm not sure this is possible. By default shows LOCK_ICON as
icon and FAIL_ICON as content. P9K_NORDVPN_STATUS is set to the
actual status (neither empty, "Connected" nor "Disconnected").

Fixes #133. Needs more testing.
