DoDeDoDo Holder

I needed a nodeMCU and RC522 case for a project and modified dgoma's case to give more room between the nodeMCU and RFID reader as it seemed to cause some interference.

Build instructions for the DoDeDoDo are [here](https://shaddowland.net/2018/11/26/dodedodo-production/) if you want to build an RFID stats tracker.
