Add Github Action Compile Tests

[latchdevel]

Hi!.

I add a Github Action to compiles the library with all its examples, which I think is useful, so I would like to share them with other users.

The Github Action compiles all examples in different platforms like Arduino Nano, Arduino Mega2560, ESP8266 Wemos D1 and ESP32 NodeMCU-32S, to at least, be sure that compilation is successful.

It is necessary to take into consideration several points:

• ESPiLight library is only functional for ESP8266 and ESP32 platforms, not work on common Arduinos AVR.
• ESPiLight library (current v0.17.0) is not compatible with ESP8266 v3.x.x environment, so v2.7.4 is forced to be used.
• RC-Switch library uses ReceivedInverted() and getReceivedLevelInFirstTiming() functions, that are not available in the main library distribution, being necessary to use "protocollessreceiver" branch from repository https://github.com/Martin-Laclaustra
• NewRemoteSwitch library must be up to date, at least on commit c3ca4cb (Sep 19, 2021), to work properly.

Hope I can help other users with my little contribution.
Regards!
