DiscoDOS v3.0.3

3.0 PyPI package was faulty due to a number of outdated things around how DiscoDOS was packaged. Some tiny feature fixes too:

• Packaging changed from using pbr to regular setup.py
• Added dependencies in setup.py via install_requires
• Fixed stats command collection counts and added sales stats
• Bring back accidentally deleted discosync tool
• Added non-python files in setup.py via package_data (ls_tui.tcss Textual stylesheet file)

(3.0.1. through 3.0.2 were iterations to finally get a working package)
