Excel Column Name Generation Bug
The logic around converting column indexes and counds relies purely on a conversion between int and char. This works well when the column index is < 26, however as Excel would go to wrap to column AA, the CellName property returns '['. This bug is also
present in the FiftyNine.Ag.OpenXML.Excel.Utilities.Formatting static class as the total size of the spreadsheet is determined.
