Add an end() function to close the serial communication #131

I modified Adafruit_Fingerprint.cpp and Adafruit_Fingerprint.h to add the end() function. It works like begin() but the baud rate doesn't have to be specified. I needed this modification for a project where the fingerprint sensor can be turned off using a switch to save power.
