make B4J sub for POI XLS - working with pictures

Hi, All

Task was here: https://www.b4x.com/android/forum/threads/xlutils-read-or-view-images-in-xls.137774
It needs to get pictures with the cell coordinates, where the picture is placed.
Many POI Java codes on the Internet, using "DrawingPatriarch".

So, the commercial coder is needed. I guess, some Reflection code would be OK.

Offer is processed. Thanks to @EnriqueGonzalez !
