Update libhydrogen & argz

• argz was updated.
• libhydrogen was updated.
• init command has a new opslimit option to change the number of iterations to perform when deriving secrets.

A new release to make your (ok.. my) life easier:

• Agent is more robust when things go wrong.
• Check passphrase for deterministic secrets too.

This new release allows you to:

• Look for a substring when listing keys.
• Pipe secret with itself.

A new day, a new release!

• Improves the handling of multiple passphrases when starting the agent with an empty store.
• The store is no longer locked when you just want to read it.

Yeah! First security fix :°

• Fixes a modulo bias when generating/deriving passwords.

This is a small release to improve the user experience :)

This is a more friendly version of secret:

• Ask confirmation for new passphrases.

• Support key renaming with the reset command.
• Support completion for yash.

One day, one release ^^

• Refuse empty keys and explain restrictions.
• Add some randomness when storing a new secret.
