Subject: [PATCH] Fix: Add Wi-Fi toggle workaround for macOS Sonoma 14.4+ (#43)

On macOS Sonoma 14.4 and later the airport command line tool no longer
works. It was being used to disassociate from any wireless networks, a
required step before using `ifconfig` to change the MAC address. Now the
only way to directly disassociate is with Apple's CoreWLAN framework in Swift or
Objective-C.

A workaround for this JS-only package is to just turn off the airport
device to disassociate from any networks, then turn it back on so we can
change the MAC address. The change is able to occur before the airport
device reassociates. This should be backwards compatible with older
versions of macOS.
