Add Package CaptainCaption

[DenRakEiw]

Hey, that's awesome that you've added onetrainer alongside Kohya. Now, the only thing missing is a tool to cover the entire training process, namely CaptainCaption. With CaptainCaption, you can create the most precise captions quickly with multiple workers, as it utilizes GPT for capturing. Could you consider adding it as a package? That would make Matrix truly complete! 😉
