Always opt for linux musl binary, automate release process

[sgb-io]

Aims to fix #42 #41 #18

• Swaps out GNU linux targets for musl - main reason is to have the C stdlib shipped statically
• Adds automated tests of the binary
• Adds automation for publishing the project, greatly simplifying the release process

TODOs

• Tests to verify the binaries work on a number of platforms
• Update MAINTENANCE.md
• Verify / test the release changes
  • Implement an npm publish dry run workflow using Verdaccio
    • Consolidate the two workflows: 2 or 3 separate npm publish steps doesn't work when it comes to the real release
  • Copy extraction solution from dry run workflows to real release workflow
  • Verify the new binaries work on the gitlab runner
• Bump versions and update changelog ahead of release
