Support "cargo release"

[orf]

cargo-release is pretty awesome, and it seems github actions would be perfect to build releases across multiple operating systems.

Can we bake cargo-release into this workflow, or provide a way to use it?

Hey, @orf, release activities are discussed at the #6, let's group the collective ideas in a one place.

I'm going to close this one issue, but I would love to hear what are thinking about these questions specifically.
