Remove wifi-scan & wifi-heatmap-threshold commands?

[plenaerts]

I've created draft debian packages for wifi-survey-heatmap, libnl3 and iperf3-python.

I propose to not install the wifi-scan and wifi-heatmap-threshold commands. They don't seem needed.

wifi-scan seems broken even. If I just run it I get an error:

» sudo wifi-scan -v wlo1 myiperfserver
Traceback (most recent call last):
  File "/usr/bin/wifi-scan", line 8, in <module>
    sys.exit(main())
             ~~~~^^
  File "/usr/lib/python3/dist-packages/wifi_survey_heatmap/scancli.py", line 114, in main
    CliWrapper().run(args.INTERFACE, args.SERVER)
    ~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/wifi_survey_heatmap/scancli.py", line 56, in run
    c = Collector(ifname, server)
TypeError: Collector.__init__() missing 1 required positional argument: 'scanner'

I've the impression that the Collector class constructor interface changed and that scancli.py doesn't give the right args.

So. I propose to drop these two commands.
