Add support for Opportunistic Wireless Encryption (OWE)
OWE provides a more secure way to associate with public access points and was defined in RFC 8110.
The interesting case is probably where the transition mode (part of the WPA Alliance specifications) is in place, where the beacon from the open VAP reference the OWE VAP, so devices that support it can upgrade to use that instead. This is something taht would need to be represented properly in the UI, so one can prefer a secure OWE network over an open one. Without the transition mode the open VAP will just be dropped and the OWE VAP will send out beacons instead.
Support is both present in iwd (from 0.12, some changes after 0.14) and wpa_supplicant (from 2.7).
