AES encryption demo and secure TCPClient usage

Here’s a little demo that you can paste into Spark Build that shows how to use the AES-128-CBC encryption already available in the Spark Core firmware. Put that on a Core and watch what it says on Serial. Once every 10 seconds it will create a random encryption key and will print a message plain, then encrypted, then decrypted. The open source AES implementation is from tropicssl in the core-communication-lib if you’re curious, and typical usage internal to the communication library is thro…

Alas I could not compile the code in the demo...
