R2D2 Alarm Clock

This is a remix based on R2D2 Clock & Timer from jeje95
I've used some different configuration from the original version:
* Arduino nano (instead of ESP)
* RTC module
* Nano shield for connections

Basically it uses the rotary encoder button to configure alarm as you can see in the following video:

The alarm plays mp3 R2D2 sounds and turn on the leds in the head. You can stop the alarm clicking in the button of the rotary encoder:

I've used different libraries to simplify the code:
* RTClib (clock)
* RotaryEncoder.h (alarm configuration mode & setting)
* ezButton (rotary encoder button)
* TM1637Display (blue display)
* SoftwareSerial (used with DFPlayer module)
* DFRobotDFPlayerMini (mp3 module)
* EEPROM (save configured alarm)
* LED (R2D2 head leds)
