Starts up the Pico W and has it listen on port 1234

Any TCP request will be responded to with 4 u16(16 bytes) adc raw reads in the order:

1. Internal Temp Sensor
2. GPIO 26
3. GPIO 27
4. GPIO 28

While this can be configured with any external hardware, the current setup is:

• LM4040 3V ref across ADC_VREF and GND
• GPIO 28 is tied to GND
• GPIO 27 is tied to 3V
• GPIO 26 is read via a voltage divider of 22.3k / 3.3k
