This is a change which is very much hardcoded for my setup, but the vpn
block will now give preference to displaying individual VPN types from
top to bottom:
If privateinternetaccess is connected, it will display its icon.
If proton is connected, it will display its icon.
If netbird is connected it will display its icon.
If nothing is connected it will display nothing.
It is still quite a hacky solution and should also be replaced by a
signal-driven system instead of the recurrent polling it does currently
(it only polls once a minute atm, to keep system load/battery drain low
but since it invokes a lot of external commands, e.g. piactl and
netbird, it should really only be invoked on vpn changes).
Using the 'alt' json return field to set the icon and change the icon
within waybar itself instead of doing so manually in the script. This
makes us a little more flexible and puts all the 'what' is rendered that
is specific to waybar into waybar (keeping the 'how' it's rendered in
the style.css).
Since the existing wayland module basically describes everything about
my 'desktop environment' setup already anyway, might as well rename it
accordingly. Additionally, mako is important for notifications in this
environment so it moves here as well.
