v0.12.4

• Changes
  • Added VintageNetWiFi.network_configured?/1 helper function for checking
    whether a WiFi connection to another computer is possible or just scanning
    for access points.
  • Added VintageNetWiFi.qr_string/3 to create QR Code-encodable strings for
    easily sharing network credentials.
  • Added experimental VintageNetWiFi.capabilities/1 to query WiFi driver and
    wpa_supplicant capabilities. This can be used to check WPA3 compatibility,
    support for 5 GHz channels and more. It's experimental since the information
    is currently very raw.
