* `void setPairingCode(const char *s)`
* sets the Setup Pairing Code to *s*, which **must** be exactly eight numerical digits (no dashes)
* example: `homeSpan.setPairingCode("46637726");`
* a hashed version of the Pairing Code will be saved to the device's non-volatile storage, overwriting any currently-stored Pairing Code
