Fast Transmission flags are not handled correctly

[tonnenpinguin]

Describe the bug I noticed a bunch of warning messages when the router sends 802.11r Fast Transmission flags.

The connectivity works fine and I'm not quite sure this is a problem. But given that these messages are printed about every 7 seconds I figured I'd report it anyway :)

11:25:00.960 [warn]  module=VintageNetWiFi.WPASupplicantDecoder [wpa_supplicant] Unknown flag: "WPA2-PSK+FT/PSK-CCMP"

To Reproduce Tbh I'm not sure how that specific network is setup

Expected behavior For the flags to be handled gracefully

It's a custom rpi4 image build with some minor modifications that shouldn't impact the networking stack.
