feat(github): added workflows for ci and crates.io publish

[lriesebos]

I am not an expert on github workflows or publishing to crates.io, so this might need some testing and a few iterations to get both workflows to run.

closes #26

I'll add a openid connect entry for it

@gz , let me know when the credentials are configured and this can be merged!

should be good to go

if you want to make a release you'll have to explicitly approve the action running under theActions tab (because it's in the release environment)

Looks like almost there but we forgot to add the cargo registry token here is how I do it in another repo

      - name: Run cargo publish
        if: ${{ vars.RELEASE_DRY_RUN == 'false' }}
        run: |
          cargo publish ${{ vars.CARGO_PUBLISH_FLAGS }}
        env:
          CARGO_REGISTRY_TOKEN: ${{ steps.auth.outputs.token }}
