Add Multiple License Files

[MasonStooksbury]

Hello there! I noticed that this repo has two licenses on it. Not sure if you knew, but GitHub made it so that you can upload several license files and it will show them without issue on the right hand side. Here is an example from one of my repos (https://github.com/MasonStooksbury/Hex-Clock)

The badges you see in my README can be added using this text. (They double as links to the license text as well):

[![License: CERN-OHL-P-2.0](https://img.shields.io/badge/Hardware_License-CERN--OHL--P--2.0-blue)](https://opensource.org/license/cern-ohl-p/)
