/**
* XF - Extended Format
*
* This record contains formatting information for cells, rows, columns or styles.
* According to http://support.microsoft.com/kb/147732 there are always at least 15 cell style XF
* and 1 cell XF.
* Inspection of Excel files generated by MS Office Excel shows that XF records 0-14 are cell style XF
* and XF record 15 is a cell XF
* We only read the first cell style XF and skip the remaining cell style XF records
* We read all cell XF records.
