Adding a picture to excel sheet doesn't work in the slightest and hasn't across last 2 (major) versions at least.

Bug description

final image = File(p.join(Directory.current.path, 'map.png')).readAsBytesSync();
sheet.pictures.addStream(15, 1, image)

^Results in late initialization exception on lastColOffset.

final image = File(p.join(Directory.current.path, 'map.png')).readAsBytesSync();
sheet.pictures.addStream(15, 1, image)..lastColOffset = 0..lastRowOffset = 0;
final fileName = _createFilename(taEntry);
final bytes = newExcel.saveAsStream();
final File saveFile = File(p.join(exportDirectory.path, fileName));
saveFile.writeAsBytesSync(bytes);

^Results in a corrupted excel file with seemingly incorrect or malformed drawing1.xml and excel reporting:
"We found a problem with some content in [file] Do you want us to recover?"
-> Click Yes and reports:
"Repaired Records: Drawing from /xl/drawings/drawing1.xml part (Drawing shape)"
Result:
Image is located in media folder fine but is not present within the sheet and drawing xml seems to be malformed or incorrect.
