I can vouch for this change somewhat: It matches my computer's output for PSK.

Just some notes:

• The "primary channel" change is bad. It occurs under the "HT" section, which is not guaranteed to exist.
• The "Authentication suites" line might occur twice, once under the "WPA" section and once under the "RSN" section. The first occurrence would correspond to WPA1, the second corresponds to WPA2 and WPA3. That's an issue with how we extract lines instead of tree-structures, but well... it works for what we have now.
• I have no idea if it works for 802.1x/EAP. It probably does, considering it also builds on WPA and RSN.
• It probably does not work for WEP. I don't have a neighbor that uses it (good for them). According to https://stackoverflow.com/a/17880517, it's indicated by a "WEP:" section.
