WiFi Magnetic Compass 2

Under construction
The Arduino MKR 1010 of the first compass version had its RF front-end broken, perhaps by an atmospheric discharge, so the WiFi no longer worked. Rather than replacing the board I investigated if the MKR 1010 could be replaced by something cheaper, and I came out with a solution based on the ESP8266 chip. At the same time I changed the Telnet readout with a more practical Web readout. The new compass still uses the the Olimex HMC 5883L board and no attempt was made to use the more recent chinese clones.
