Install Go (v1.16beta) on Apple Silicon, use with Homebrew

Go is not available to install via Homebrew at the time of this writing. (Dec 18th 2020)

Go v1.16 will ship with Apple Silicon support in February of 2021, however the Go 1.16 beta can be installed from the Go website and can be linked to brew so that other brew packages that depend on Go may use it.

1. Install go1.16beta1.darwin-arm64.pkg.
2. Run mkdir /opt/homebrew/Cellar/go
3. Create a symlink to the Go v1.16 pkg installation with ln -s /usr/local/go /opt/homebrew/Cellar/go/1.16
4. Run brew link go
