Lots of changes to allow this script to scan on existing stations
on multiple resources.
Add --use_existing_station option.
Fix help to show how to properly specify multiple stations with
--sta_name
Comment out convoluted logic that tried to find radio info for stations.
This is not needed for any purpose that I can find, and it did not
allow me to specify sta_name with EID format.
Start scan on all stations, then do sleep time, then grab results.
This allows concurrent scanning on multiple resources/radios.
Print more info in text based output, add station resource and name
to output so we can decipher multiple radio output.
Add note about how .csv output is broken in this case, the logic
needs to be improved to append results for all stations and write a single file.
Add --scan_time argument to specify sleep time (defaults to 15 seconds
to match the original hard-coded value).
