Updates to parsing large timeout values (hours and days)

* Fixed parsing of hour-log timeouts, e.g., `4h`.
* Added day-long timeout, e.g., `1d`
* Added week-long timeout, e.g., `1w`

The long timeouts are useful when using the `--stop-after-time` command
line flag, where you want to fuzz e.g., for a couple of days and then stop.
