WLAN beacon implementation

BluemarkInnovations commented 2 years ago

First PR of the WLAN Beacon implementation.

~~Beacon functionality only works if also WLAN NaN is enabled (and the web interface). Needs more testing, it seems that without WLAN NaN, the module uses channel 1 and the PR doesn't work.~~
~~Need improvement, so the module transmits also WLAN Beacon packets if the web interface is disabled.~~
The Beacon update rate means that the RID information is updated with this rate. Default an AP transmits every 100 ms a Beacon packet.
Added the probe response implementation. This is the default mechanism (probe request/response) for smartphones to detect nearby APs. Without the probe-response implementation, the user experience/update rate is horrible on most phones. With the probe response implementation and on the smartphone, WiFi scanning throttling off (Developer options, see the OpenDroneID project), performance is acceptable.

Fixed outstanding issues

BluemarkInnovations commented 2 years ago

made the wifi channel a parameter
code clean up, some calls were not needed
the issue/bug was that the web server did have its own default configuration values, not using the configured ones, solved in this PR
use the random generated MAC address also for WLAN packet generation instead of the device MAC address
added separate counters for both beacon and NaN packets
