Fuzzer could send status notification on crash / daily

[louismerlin]

Ziggy could be given an API key through ENV or the CLI, which it could then use to send out notifications to the user.

Ideas for the notification platform include:

• Discord DMs (probably requires creating a "discord bot")
• emails (probably requires using a third party service)
• GitHub issues (requires a target repository)

or easier: -c cmd option which executes the command with x parameters. then the user can decide for themselves how they want to be informed.
