Add some CI workflows
Created by: tobiaslcmueller
I added three github workflows:
- CompatHelper will scan regularly all dependencies and open a PR when detecting a breaking change (i.e. new major version)
- The RegisterAction automates Registering the package with General: Simply go to the actions tab, enter the version umber you want to push the package to (or alternatively the part of the version to be incremented, i.e. "major", "minor" or "patch". and it will automatically generate the according PR
- TagBot will git tag and Github-Release any new Version registered with General.
Any workflows we should add? Automatic testing after pushing?
Closes #29 (closed)
