Add console_scripts/pipx support to installation

[xtaje]

Adding support for console_scripts to the setup.py will make this more easily accessible to non-python developers, as may happen in CI, for QA teams, etc. https://python-packaging.readthedocs.io/en/latest/command-line-scripts.html#the-console-scripts-entry-point

It will also make it automatically compatible with pipx, which prevents installation conflicts and problems. https://github.com/pipxproject/pipx
