Feature Request: Lower clock of ESP12 to compress and hide the 2.4GHz radio

[jwcrawley]

As an "evul hacker", I;'d like to underclock to compress the 2.4GHz waveform, so that it requires another ESP12 with the firmware to even see the SSID let alone the data.

A writeup how to do this is https://hackaday.com/2019/01/04/underclocking-the-esp8266-leads-to-wifi-weirdness/
