Flag to stop stream and discard delay

[peppy]

In OBS, if you have a stream delay, there is the option to stop a stream normally, or stop and discard the delay/buffer. It would be great if this could be supported in obs-cli.

Use case: on macOS, OBS doesn't handle global keyboard shortcuts. I'm using obs-cli to workaround this issue (in conjunction with skhd for binding commands to keys) but am missing the ability to quickly halt my stream to avoid showing potentially confidential data. I still have to reach for the button on the OBS interface currently, or force kill the app.

This is already available in the OBS hotkey binds list, for reference:
