Package SerializedDataSetViewer with DBA Dash

[DavidWiseman]

SerializedDataSetViewer can be used to view the xml files that DBA Dash writes to S3 or folder destinations. DBA Dash also writes these files to the Failed folder if there is an issue writing data to the repository database. In some cases, there might be a data issue that prevented the import and the SerializedDataSetViewer can be used to help troubleshoot this.

Currently, this is a private repo under my own profile.
