go concurrent bssid scanner

[randomizedcoder]

Thanks for this repo!

I "borrowed" code from this repo to implement a go concurrent BSSID scanner.

https://github.com/randomizedcoder/go-bssid-geolocator

Using this overnight I scanned and found ~91million

[das@t:~/Downloads]$ cat 2025_03_18_1640 | grep -v generateMACs | grep -v "Lat: -180.000000 Long: -180.000000" | wc -l
91273223
[das@t:~/Downloads]$ ls -lah 2025_03_18_1640
-rw-r--r-- 1 das users 9.2G Mar 19 14:50 2025_03_18_1640

Example of output

If you are interested, possibly I could send you an MR to add my code into your repo

Thanks again

This is pretty cool. It would be interesting to combine the approach of scanning OUI ranges and using wifi tile as seeds to get the largest set of data possible. Currently a bit busy but I'll have a look once summer break starts.
