Update example code to use recommended 160 bits (#3088)
I found the examples with `os.urandom(16)` generated URIs that Google Authenticator and Duo two-factor apps did not even recognize as supported. This increases the key to the recommended 160 bits, and the URIs now work with both of those apps.
