Adding a rails-like destroy option to the cli

I'm definitely liking what I've seen of Blitz so far, but I'd love to see something similar to rails destroy and its alias rails d added to the cli. Right now removing a model requires editing the schema and running a new migration which is fine but a little clunky and adds extra steps when you might want to remove everything related to it. Having a way built into the cli to remove anything made by blitz generate would be really convenient.
