WIP: Parse csv files to populate default player table in a sport

@ShaiNirShado 

Basically this is mainly a PR for checking the code; currently this does work but the code is currently pointing at a specific .csv file at the root folder. The new branch that builds on this one will change the target to run on a single default_players folder that contains all the csv files to parse through them and run this code on each.
It would be nice to have a comment somewhere with the format that the CSVs are expected to have.
