Disconnecting after X minutes of inactivity.

Is your feature request related to a problem? Please describe.
I love the bot, but when I forget to tell it to exit, it stays on, using up bandwidth.
I would love for the bot to automatically disconnect if there is no activity for a certain period of time, in order to save data and processing. Especially if people end up inviting the bot to other servers, I don't want the bot to be in the channel alone.

Describe the solution you'd like
Maybe the problem I'm describing is already fixed since I haven't waited long enough, but an option in the .env file for a disconnect time would be great. Possibly by checking how long the queue has been empty for, and after the time in the env is exceeded, disconnect automatically.
