Test speed (i.e. battery life) improvements with persistent BearSSL sessions

With ESP8266 Arduino-core 2.5.0 we may be able to serialize the BearSSL::Session object to RTC RAM and restore it before trying to (re)connect. Should give a significant speed (and thus battery life) boost.

In this context I would love if we could extend the headers the client sends by a field which measures the full awake time of the last cycle.

We should keep this open and also consider the other recommendations in that great documentation page.

it is recommended that all TLS/SSL sketches to run at 160 Mhz and not the default 80 Mhz.

wrt energy: higher CPU speed vs. shorter air time
