fix python packaging using latest methods

- Change python packaging method following instructions from
  https://packaging.python.org/en/latest/tutorials/packaging-projects/
- Remove scripts as they can be created automatically from setup.cfg
- move the sources to src
- setup.py: remove captialization in package names, conflicts with other
  packaging methods like debian's
- modify licence to gpl3+
- Add setup.cfg and pyproject.toml
- modify MANIFEST.in to include assets
- WoeUSB-ng.desktop: add version and change icon
