Logger -- make print to USB, test storage functions

[LizzyMilford]

1. Change the file path in Logger class to print logs to a thumb drive. Test with a robot and a thumb drive. Check that no logs are going onto the RoboRio.
2. Test printing Rio storage as a percent on the shuffleboard. Check for accuracy.

OPTIONAL: if no thumb drive inserted, backup data on Rio. Test the log puller batch file to pull files off of Rio. If interested, see if the batch file can automatically run every 2 weeks or Rio storage 50% full.
