Updating math/p5-Spreadsheet-WriteExcel from 2.36 to 2.37

Upstream changes:
2.37 February 2 2010 - Minor
    + Added set_chartarea() and set_plotarea() methods to set
      chart and plot background colours and border lines.
    ! Fixed bug where embedded charts gave "Data may be lost"
      warning. Reported by Andreas Strobitzer.
    ! Fixed issue where set_properties() didn't work with ::Big.
      Marked ::Big as deprecated in the docs in favour of using
      Spreadsheet::WriteExcel directly. Removed WorkbookBig.pm.
