Offer Homebrew installation option

[kevincianfarini]

I've used powerline-go for a while now, but I've always just downloaded a binary and placed it in $PATH. It'd be awesome to get easy updates via a homebrew formula. :)

Thank you for your work!

Easily done with goreleaser. See GitHub action and config here: https://github.com/buildtool/build-tools

I'll look into it :)

I just installed it via brew so I guess you can close this issue.

I didn't realize there was an available artifact already on homebrew. However it could be extremely useful for the maintainer to assume ownership of that formula so that updates can be published as part of CI. Right now, random community members are publishing it.
