Add argument to remove original image

[Burhan-Q]

When using slash-command, would be good to remove original image so it doesn't crowd the channel too much. Could possibly edit original message or just delete original request.

Perhaps instead of adding an argument, have the bot delete the original message after waiting ~30 seconds. That should help clean up the channel, but not remove images too quickly.

• For $predict message, add ~30-60s delay deletion of original image?
• Argument for /predict shouldn't be needed as original image isn't shown in chat history
