Added example test file for recs80

Completed adding recs80 sending and decoding
I have tested it using two arduinos (one for sending and the other for receiving) and have achieved a 90% (estimate) success rate.

-## 3.0.0 - 2017/09/14
- Changed default send pin on ATmega32u4 from 13 to 9.
-	Note: this is a non-backwards compatible change as the behaviour of existing programs using this board for receiving WILL be affected. If you would like to use pin 13 as before then please search src/boarddefs.h for "32u4" and comment the line for pin 9 while uncommenting the line for pin 13
