darwin-arm64 build?

[bryanvaz]

A bit of a self-centered request, but wondering if you could add a darwin arm build to the release assets?

(I'm setting up my new machine and realized I built it from source last time, but I don't have the go toolchain on my new machine :D)

Cheers!

Hi, I'm afraid I don't have an Apple computer to test the results. If you would like to contribute a PR is welcome!
Cheers!

I submitted PR #15 which adds MacOS arm64 builds plus windows arm64 builds.
