Support mas cleanup

[jeromebaum]

According to the nix-darwin documentation, brew bundle cannot currently clean up mas applications. Is this a design choice or a technical challenge? If a technical challenge, could you explain a bit more about what's tricky & whether you'd be open to a patch to fix this?

I think this was probably just never implemented. It's possible it doesn't work but we're definitely open to a PR to attempt implementation.

I started on this. Now I realise why it wasn't implemented before. 😅 I found that mas uninstall requires root permissions, and it doesn't always work. In fact, it didn't work at all in my testing (this issue is what happened).

This is not possible. Unless we want to try to fix mas. But by the looks of its README and the issues that I linked above, Apple has been slowly cutting off the APIs that mas uses and mas cleanup is going the same way. Shame, as I enjoyed working on that branch until I realised it was non-functional.

I'm going to watch the relevant mas issues and open another issue if/when this gets fixed in mas. It does look like there is some hope - apparently there is a supported way to do this, though it is some effort.

Thanks for looking into it!

@jeromebaum Thanks, sounds good. If you find it's fixed then please do ping here (or another issue), I did quite a bit of work here and I'd like to ship it if the underlying behaviour is ever is fixed!
