create a brew cask formula

[muescha]

create a formula at https://brew.sh/ so that the app can easy installed with:

brew cask install menuffy

@muescha Surely it's nice to be able to install in brew! I've created a PR so I can use brew once it's merged. https://github.com/Homebrew/homebrew-cask/pull/83150

We needed more visibility to add menuffy to CASK. ( less than 30 forks, less than 30 watchers, less than 75 stars)

If the condition is exceeded, I will try again.

Yes - i read it :(

But until then you can make your own cask repo which need to register with brew tap before the cask can be used
