Async scanNetworks & begin

[produceconsumerobot]

Is there any interest/plan to incorporate an asynchronous WiFi.scanNetworks and/or WiFi.begin function similar to https://github.com/me-no-dev/ESPAsyncWebServer#scanning-for-available-wifi-networks into the mainline WiFi101?

I'm currently capturing data with a feather M0 wifi (samd21+winc1500) at moderately high rates (17 channels @ 60Hz) and saving it to an SD card. I would like to be able to connect to different wifi networks as they come in and out of range, but currently the scanNetworks and begin functions are taking about 1-2 seconds and only return control to my main loop after completion. To ensure accurate sampling, I have my data collection on an interrupt, and am double buffering data to write to the SD card in the main loop, but double buffering 1-2 seconds of data while I wait for scanNetworks/begin to complete takes a somewhat prohibitive amount of RAM for my application. If there was an async option it would be a huge boon to start a scan/begin, go back to SD card writing and then periodically check whether my network activity had completed.

I would also be happy to contribute my lab's time to this effort if there are any API/style guidelines that I should be aware of.

I discovered that WiFi.setTimeout() in 0.16.0 enables asynchronous behavior for WiFi.begin()
