Delete missing items from Brewfile

[brandonguigo]

Hi there !

I love the tool and use it as a setup as code for my macs.
I would like to know if there is any possibility to delete missing brew items from the mac if there are not in the Brewfile anymore ?

Thanks for the work !

For simple configs you can run brew bundle --cleanup --zap in a directory with a Brewfile, but this would be a good feature to add in zero for use with workspaces.

Okay, I will try to add that sometime when I have time.

Will add a PR to this issue soon.
