ESP32 Supports Wi-Fi Aware (NAN)

Mentioned NAN in a comment on Localsend, an open source airdrop alike, as a possible remedy while discussing that (nearly) none of the airdrop competitors handled the transport layer. https://news.ycombinator.com/item?id=37938336

A good number of the responses mentioned how NAN was basically not available in most hardware. Good to see this counter-examples! Of course to be a real win, we'd need broad ecosystem support, but gotta start somewhere!
