chore(ci): introduce semantic release (#241)

semantic-release will evaluate the commits since the last version. If a new version is necessary, it will update the changelog, increase the version number (if necessary), create a git tag and publish a release on npm.
It will be triggered every time something gets pushed to master.

Fixes #54 
Fixes #32
