This release I added an image viewer to the utility.

I also optimized data loading by first loading parquet data into basically a multi dimensional array which I called DataTableLite.cs. I found that generating rows one cell at a time had significant costs due to BeginEdit() and EndEdit() calls within DataRows. So this way of loading row by row provided significant speed improvement.
