Added Serial prints for file name/path

[V205Arduino]

Thank you for creating a pull request to contribute to Adafruit's GitHub code! Before you open the request please review the following guidelines and tips to help it be more easily integrated:

• Describe the scope of your change--i.e. what the change does and what parts of the code were modified. This will help us understand any risks of integrating the code.

Added the following code to both example’s setup:

Serial.println( F("Starting " __FILE__ " from " __DATE__ __TIME__));// Prints the file name and compilation date.

Just to make it easier to know what file is running.

• Describe any known limitations with your change. For example if the change doesn't apply to a supported platform of the library please mention it. No none faults yet.
• Please run any tests or examples that can exercise your modified code. We strive to not break users of the code and running tests/examples helps with this process. Seems to be running ok.

Thank you.
