Modifications to sillm.chat

[magnusviri]

I've modified sillm.chat a lot. Let me know what you would be interested in adding to your repo and I'll put those changes in my fork and do a pull request. Here's a list of changes.

• Arrow key support, including history. This requires the cmd module.
• Pressing esc while generating a reply stops it. This requires tty, termios, select, and sys modules.
• Debug messages, user chat, and assistant chat are all colored differently. The colors are not settable at this point, nor is disabling color output.
• Uses "/" to do commands. Everything else (including "." and "") are sent to the assistant.
• /exit, /help - kind of obvious.
• /seed, /temperature, /max_tokens, /system_prompt - sets the values.
• /clear - resets the conversation.
• /conversation - print the conversation.
• /rewrite - rewrite the last assistant reply and put that in the conversation (I have bug in this somewhere because it doesn't always work).
• /settings - print the settings (seed, temp, max tokens).
