This modification gives the user the ability to access the unique serial-number built into Feather M0s for whatever purpose they need (see: discussion).
Overview of changes:
Added new #define for serial no. length at top of Module.h
Added new protected character array to store serial no.
Wrote private read_serial_no method that actually reads serial number in from registers and stores it in the array
Added a call to read_serial_no in Module init
Wrote a public get_serial_no method which simply returns the serial no. in the character array
Example use:
LPrintln(Feather.get_serial_no()); // Prints the serial number
Testing:
This was tested on a Feather M0 proto basic and Feather M0 WiFi but all Feather variants use the SAMD21 chip so this should work on all Feather variants.
