Allow bot to have designated image-recognition channels so that other bot commands can be made broadly available without performance impact

My understanding is the bot is restricted to specific channels on each Discord guild/server for performance reasons related to image analysis.

However, there's no reason the bot shouldn't respond to other commands in all channels it is present in. This would be useful in the main community Discord where I frequently have to screenshot a bot reply from the bot channel, or use an alternative bot.

We don't actively restrict currently, but ask people to do so, such that we don't process will their cat pictures. If we want to change this, we probably need a proper admin panel for the bot. And therefore the actual change here is to not process images unless they are in the bot channel. The bot will reply to everything valid in all channels it is in already.

This makes sense.
