ES100-MOD WWVB 60Khz receiver

This board is for https://github.com/mahtin/es100-wwvb code.

A time and date decoder for the ES100-MOD WWVB receiver. This code implements tracking (for daytime reception) and full receive decoding (for nighttime reception). It provides Daylight Saving information and Leap Second information, if WWVB provides it.

It's written 100% in Python and tested on the Raspberry Pi4 and on the Raspberry Pi Pico W (using micropython) with, or without an OLED display.

The core ES100 library fully implements all the features described in ES100 Data Sheet - Ver 0.97.
