CLI: add 'analyze' subcommand for offline HIBP breach checks

This new subcommand checks all passwords in the given database against a given list of SHA-1 password hashes. Such lists are available from the "Have I Been Pwned" project at https://haveibeenpwned.com/Passwords.

Note that this support offline checking only. The HIBP project also provides a web API for checking specific hash ranges; this is not currently supported.
