Release as a homebrew package

[tpitale]

When popular enough (>50 stars, I think), would be great to have this as a homebrew package so one could just use brew install pgmetrics. I tried to create this package, but it requires building from source and I didn't have the time to figure that out for a go project right now. Also, they want it to be around for more than 30 days (a semi-valid concern).

+1 for this!

I had need to install pgmetrics on my MBP today and added a formula to my tap temporarily to do so. I might submit it upstream if I find time, but if someone feels like taking it and submitting upstream (along with following upstream's guidelines on naming, style) please feel free to do so.

For now, brew install caius/tap/pgmetrics should work, and that should be kept fairly up to date with new releases. https://github.com/caius/homebrew-tap/blob/main/Formula/pgmetrics.rb is the magic that makes it work.
