Added example test file for recs80

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

+# Contribution Guidlines
+
+This library is the culmination of the expertise of many members of the open source community who have dedicated their time and hard work. The best way to ask for help or propose a new idea is to [create a new issue](https://github.com/z3t0/Arduino-IRremote/issues/new) while creating a Pull Request with your code changes allows you to share your own innovations with the rest of the community.
+
+The following are some guidelines to observe when creating issues or PRs:
+- Be friendly; it is important that we can all enjoy a safe space as we are all working on the same project and it is okay for people to have different ideas
+- [Use code blocks](https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code); it helps us help you when we can read your code! On that note also refrain from pasting more than 30 lines of code in a post, instead [create a gist](https://gist.github.com/) if you need to share large snippets
+- Use reasonable titles; refrain from using overly long or capitalized titles as they are usually annoying and do little to encourage others to help :smile:
+- Be detailed; refrain from mentioning code problems without sharing your source code and always give information regarding your board and version of the library 
+
+If there is any need to contact me then you can find my email on the README, I do not mind responding to emails but it would be in your own interests to create issues if you need help with the library as responses would be from a larger community with greater knowledge!

+## FAQ
+- IR does not work right when I use Neopixels (aka WS2811/WS2812/WS2812B)  
+Whether you use the Adafruit Neopixel lib, or FastLED, interrupts get disabled on many lower end CPUs like the basic arduinos. In turn, this stops the IR interrupt handler from running when it needs to. There are some solutions to this on some processors, [see this page from Marc MERLIN](http://marc.merlins.org/perso/arduino/post_2017-04-03_Arduino-328P-Uno-Teensy3_1-ESP8266-ESP32-IR-and-Neopixels.html)

+- ATtiny 84 / 85
+- ESP32 (receive only)
+- ESP8266 is supported in a fork based on an old codebase that isn't as recent, but it works reasonably well given that perfectly timed sub millisecond interrupts are different on that chip. See https://github.com/markszabo/IRremoteESP8266
+
+We are open to suggestions for adding support to new boards, however we highly recommend you contact your supplier first and ask them to provide support from their side.
