ROBOT export generates error in large excel exports #1131

Description

@dlutz2

When trying to export an ontology with more than 64,000 classes into an Excel file, ROBOT (v1.9.4) export generated an error "The maximum number of Cell Styles was exceeded. You can define up to 64000 style in a .xlsx Workbook", which I believe is coming from the POI library. I think it is caused by the the CellStyle style = wb.createCellStyle(); call in robot.export.Row.addToWorkbook() which creates a new CellStyle for each row. The export works fine when exporting to text and html.
