Flashing MicroPython on ESP8266

Remember to ground PIN 0 for flash mode. I've added a push button to the UART-to-USB dongle for that. I then push it while plugging in.

Get the latest firmware from MicroPython Download Page for ESP8266 1MB. That's the chip I got.

In the time of writing this was the latest file: esp8266-1m-20230426-v1.20.0.bin.
