workflow: add binary build and publish action

[RiRa12621]

This PR adds an action to create binaries once a release is crafted.

As a follow up, an addition to the readme is needed, but it would make sense to ensure the workflow is working as expected, before adding the corresponding readme section.

This fixes #6

The zip and tar archive should just be a single line essentially, so that could be added to the run section. Maybe the folder should then be renamed.

We can point to a release version of the actions as well. I can dig up which are the current stable releases.

The token is a built in of GitHub that's generated at the start of a run: https://docs.github.com/en/actions/security-guides/automatic-token-authentication

Okay cool! I'm going to try to see how rough it is to just call curl directly from the script to upload the asset. Doesn't seem too bad
