Travis Build Server

For this project, we set up a Travis build server to compile the ClusterDuck Protocol Example files. Travis will tell us if a pull request or current branch has any errors in it by compiling the example files for an ESP32 device.

Travis CI is configured by adding a file named .travis.yml, which is a YAML format text file, to the root directory of our repository. This file specifies the programming language used, the desired building and testing environment (including dependencies that must be installed before the software can be built and tested), and various other parameters.

NOTE: The new Arduino CLI breaks our compilation method, we reverted back to 0.17.0
