Added support for Dream Cheeky USB Fidget device

All I had to do was remove the OPEN/CLOSE stuff from your code, and change it so that DEPRESSED = 0x1E

I've spent the last couple of hours doing my best at adding support, and have issued a pull request. 

<del>Everything seems right to me, but there's an odd error during the gem build that says "file not found" for one of my new files. Hopefully you know how to solve that one!?</del> A restart solved this phantom problem, so we're good to merge!
