Private Internet Access (PIA) VPN region chooser in Emacs

[TRS-80]

Hello *,

Some months ago, I had written for myself a completing-read style VPN
location chooser, implementing PIA's most recent API.

They do publish some F/LOSS shell scripts[0] to do this, but they
automatically choose for you the "closest/fastest" region, instead of
allowing you to choose your exit point.

Of course, preferring not to leave Emacs anyway, I implemented in
Elisp a few functions which first fetch the list of exit points, and
extract the relevant bits using jq.  Then a connect function will
present them to you in completing-read style so you can choose a
region, and then connect.  Disconnecting and changing regions is also
supported.  It's pretty basic, but it does what I need.

I have been using this for some months now without issue.  Publishing
them publicly would involve a minimal amount of polish and writing a
README, which I could be bothered to do if there is enough interest.

Cheers,
TRS-80
