### API
* `generateKey()` generates a 32-character (160-bit) base32 key
* `generateToken(formattedKey)` generates a 6-digit (20-bit) decimal time-based token
* `verifyToken(formattedKey, formattedToken)` validates a time-based token within a +/- 30 second (90 seconds) window
* returns `null` on failure or an object such as `{ delta: 0 }` on success
