Raspberry Pi (3/4) case with support for Zigbee module

Customizable cases for the Raspberry Pi 3B and 4.

Designed for use with [this zigbee module](https://shop.codm.de/automation/zigbee/33/zigbee-cc2652p2-raspberry-pi-module) and an [antenna adapter](https://shop.codm.de/antennen/2.4ghz/7/u.fl-sma-antennenadapter-10cm) from [cod.m](https://www.codm.de/).

The antenna adapter holder can be disabled in the customizer, along with some other cutouts and tolerances. Please see the comments in the customizer.
