Title: Fixed issue with hidden files getting checked in sequence/avro data sources

- Added new optional PathFilter argument to Helper.getFileStatus and
Helper.pathExists. Default behaviour is to ignore hidden files, ie.
those that start with "." or "_".
- Added test case to verify the default filtering works.
