Publish the binary on Homebrew

[ELLIOTTCABLE]

So, "compile the binary and save it somewhere," while totally making sense for a little one-off throwaway script, ain't great for reproducible / stable system configuration that lasts past the current machine's lifetime. :P

Any chance you're willing to see this shipped to Homebrew or similar, as simple as it is?

Hey @bouk - any feedback on this?

There's a CLI dark-mode setting command in Homebrew:
https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/dark-mode.rb

Figured it may be worth a look to see if you're interested in having this very awesome notify version added to it's own homebrew recipe?
