This release implements the following changes:
* a repackaging according to modern post-PEP517 python packaging standards, hence builds are now isolated by default and dependencies (moviepy) are automatically installed.
* various quality of life improvements such as automatic detection of file extension, a `videogestalt` command directly installed in the environment, and the possibility to use videogestalt as a Python module.
* a basic unit test with branch coverage.
* a continuous integration and continuous deployment GitHub Actions workflows, to automate unit testing and deployment to PyPi.
* a logo.
