Add error checking to jetson serial application

[ZachTurner07]

At the moment, the Jetson commands the Arduino to begin executing continuously regardless of its response in the isConnected() function. Error checking could be added here to not continue if the reponse isn't matched.

DoD: Add error checking so that the application exits if the response isn't correct.
