Move project metadata from setup.py to pyproject.toml.

`pyproject.toml` is the recommended way to describe projects and to declare
metadata such as its dependencies
(https://packaging.python.org/en/latest/specifications/declaring-project-metadata/).
This change also updates the PyPi version which was severely outdated (as
highlighted in issue #116).
