BirdNET-Pi case for Orange Pi Zero2

[BirdNET-Pi](https://github.com/mcguirepr89/BirdNET-Pi) is a realtime acoustic bird classification system for the Raspberry Pi 4B, 400, 3B+, and 0W2.

This is clearly a project for outdoors, so this case is intended to house the hardware.

Hardware list:
* [Orange Pi Zero2](https://www.amazon.com/gp/product/B0B9BVTLWQ/) - you don't need the case or the expansion board. I got the heat sink and power supply.

* [TRRS Audio Plug](https://www.mouser.com/ProductDetail/474-COM-15337) - If you go with a different sound card, you might need a different plug
