Update Pycom WiPy Firmware From Commandline

WiPy is a pricey but good quality ESP32 development board from Pycom. I got mine from Pimoroni. Pycom does offer their own firmware updater but for my taste it has bit too much magic going on. I prefer to do things from commandline and I stay in control to see exactly what is going on. Quick Googling did not reveal anything so I decided to document my upgrade procedure.
