Specifying `--verbose` tends to give segmentation fault

$ dashing2 sketch --verbose

I don't think there's a verbose option currently. We could add it in (maybe change the VERBOSE_ONLY macro to be controlled by a runtime parameter instead of a macro) or add in some logging and control it via a flag.

This should be fixed now. (The --verbose option doesn't do anything currently, but there's no segfault.) Similarly, there is now a check for unexpected CLI arguments, so an error will be thrown instead of SEGV.
