Default digits to 6 and time step to 30 seconds. This implies passing
`-d 8' to all TOTP test cases.

Fix test cases for TOTP
...
RFC 6238 isn't clear enough in the Test Vectors section, and the
different HMAC algorithms use different secrets.

Change totp to take a uint64_t instead of time_t
...
Let the application deal with converting time_t to uint64_t. For TOTP,
it's just a counter.
While there, rename 'granularity' to 'step', as it's used in RFC 6238.
