Version 0.1.1

Changed

• Added pipenv files to establish a well-defined development environment: In particular, the Pipfile describes the dependencies of the library (or rather, application for the sake of the development tasks) and the Pipfile.lock locks down the dependencies and subdependencies to specific versions. (#14)
• Updated numerous security-related indirect dependencies in Pipfile.lock (#22)
• Migrated from Travis CI to Github Actions (#23)

Fixed

• Fixed bug where wrong item from an imported tvgutil contact plan would be interpreted as delay. (#15)
