* Implement the BD_ADDR(char * address_string) constructor.

* Updating implementation to use sscanf.

There is an extra step after the sscanf that checks that we got
six bytes back and if we did not, it will set all bytes in the
address to zero.

* Example using BD_ADDR(const char * address_string)

This example shows how BD_ADDR(const char * address_string) can
be used to create BD_ADDR objects to use for comparisons etc.

* Update LEDeviceScanner.ino formatting
