Fix hard coded default wi-fi interface about m-cli HOT 2 OPEN

First off, thanks for raising this!

🤔 Ooh, configuration. We've not needed any thus far, so this is an interesting proposal.

Normally I'd be reluctant to add a config file for one setting, but I agree the other options are a little... lame. The other option is a runtime flag '-i interface', ala wpa_supplicant.

If you want to put a RFC/PR for a config proposal, it'd be good to see what that'd look like before we completely commit to it.

Here's a vote for a command-line based parser thing like the first option. It's what I used in a previous PR (#135) and if it helps, this might be a little less ugly:

system_profiler SPNetworkDataType | grep -A1 AirPort | grep -o en.
