Workbook properties

Write document properties into the xlsx. They appear in Excel's "File → Info → Properties" panel. There are two kinds:

• Standard properties — fixed fields defined by OOXML (title, author, company, etc.), written in one call to Excel::setProperties.
• Custom properties — user-defined name / value pairs, written one at a time via Excel::setCustomProperty.
