Restructured project to better run as a package.

This should have been setup correctly, but now try to better follow
structure for python modules, which this is supposed to be.
- Renamed folder from src -> seasonedParser
- Moved test/ into seasonedParser/
- test has __init__.py script which sets location to the project folder
(seasonedParser/).
- Removed cli.py and moved contents to __main__.py
- Updated drone to run pytest without test folder parameter
