Allow Region option

[JasonMeudt]

Can you add in the option to request a region/server via the case block?

	"-l"|"--location")
		shift
		LOC="$1"
		shift
		;;

and then in the if [ -n "$OPT_SHOWHELP" ] block, add:

echo " -l, --location <region> Specify the region/location for the WireGuard config"

It would be overridden by the user config file unless it was put in a separate variable (eg LOC_CMDLINE or so) and pulled in after user config is read around line 113 (eg if [ -n "$LOC_CMDLINE" ]; then LOC="$LOC_CMDLINE"; echo "Location overridden by commandline to $LOC_CMDLINE"; fi or so).

I'd accept a pull req if you fix that, since the default user config includes a location and thus your edit as described would confusingly/silently not work 😉
