Switch to GitHub Actions

[loekd]

• Downstream dependencies are now monitored by Dependabot.
• Builds are now done in GH Actions.
• Versioning is now based on SemVer and conventional commits can be used to make changes other than simple patches.

  • The commit contains the following structural elements, to communicate intent to the consumers of your library:

    fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning).
    feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning).
    BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.
    types other than fix: and feat: are allowed, for example @commitlint/config-conventional (based on the the Angular convention) recommends build:, chore:, ci:, docs:, style:, refactor:, perf:, test:, and others.
