Feature Request: Add Franz Producers to Bot API

[control-o]

The current bot API lacks support for Franz producers. Adding producers to the bot API would help make for interesting commands, giving them the ability to communicate with points-term, for example. Let me know if there's interest, and I'd be glad to send a PR.

Thought a bit more about the implementation and I think adding producers directly to the bot is not a great idea, either the term needs to send the output of the command back to the bot or the term directly send the chat messages, making it a pain to manage what the code is doing in the two places.

To avoid the round trip and make the code more manageable what could be done it to have one shared library for commands and sending chat messages that the bot and points-term both use

• shared command lib that checks for valid commands ( with distinction on where they get run, maybe an enum, or structs for term and bot commands )
• shared twitch API lib for sending messages
