feat(versioning): enforce conventional-commits and add release script

[maeertin]

This PR adds following:

• Commit message linting which enforces the conventional commit standard.
• Interactive commit message helper which helps formatting based on the conventional commit standard.
• yarn release script which bumps repo version based on commit messages and generates a CHANGELOG file.

Thoughts? @alexanderflink @vincentboiardt

Missing currently in PR would be to update the README detailing how to use the new release script. This has now been added.
