Feel the noise on a Raspberry Pi Pico - learn to play .wav and .mp3 files in CircuitPython

We'll learn that you can attach an audio jack to a Raspberry Pi Pico and Pico W with simple alligator clips, then get sound to play from the Pico through the speaker. We'll learn to do this for wav files and for mp3 files. We'll write re-usable routines that you can copy & paste any time you want to play these types of files in your own builds. We'll learn how to use Audacity to create .wav and .mp3 files that will play via CircuitPython. And we'll learn how to use Python's ternary operator to write shorter, more efficient code. Crank up the Big Learning - this one goes to 11!
