Is your feature request related to a problem?

Simple examples are often used for quick debugging or function testing.

But currently the output of the WiFiScan example is not very useful:

Setup done
scan start
scan done
17 networks found
1: IoTNetwork (-62)*
2: WiFiSSID (-62)*
3: B3A7992 (-63)*

It does not show what the esp32 board recognizes, like encryption or channel.

Describe the solution you'd like

Add more useful data to the output.

E.g

Setup done
Scan start
Scan done
17 networks found
Nr | SSID            | RSSI | CH | Encryption
 1 | IoTNetwork      |  -62 |  1 | WPA2
 2 | WiFiSSID        |  -62 |  1 | WPA2-EAP
 3 | B3A7992         |  -63 |  6 | WPA+WPA2
 4 | WiFi            |  -63 |  6 | WPA3
 5 | IoTNetwork2     |  -64 | 11 | WPA2+WPA3
