[Raspberry Pi Pico] I implemented the network function! !! You can use the API by WebClient or HTTP

I tried to implement network function using Raspberry Pi Pico and CircuitPython. Starting with automatic IP address acquisition by DHCP, HTTP Web client function and GET / POST communication are also possible. Now you can use the Raspberry Pi Pico as an IoT device.

* About the Master / Slave name of MOSI / MISO
MOSI is generally an abbreviation for Master Out Slave In, but nowadays the word Master / Slave tends to be judged to be unfavorable for human rights.
Therefore, this video also avoids the word Master / Slave and uses the word Microcontroller / Sensor according to the definition in Adafruit (CircuitPython).
