Row breaks not working when print area is set starting from non-A column

[peterlamfs]

This is:

- [X] a bug report
- [ ] a feature request
- [X] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

After setting print area starting with a non-A column (e.g. B1:B2), calling setBreak('B1', Worksheet::BREAK_ROW) should be able to split B1 and B2 in two different pages.

What is the current behavior?

B1 and B2 appears in the same page in print preview.

To have a correct row break for non-A column, min="1" max="(count of print area columns)" should be added to the <brk> element in xl/worksheets/*.xml. These two attributes can be referred to the XML standard.

This seems like a bug in Excel. It surfaces in unit test Reader/Xlsx/RowBreakTest.I think we can code around this/ Reopening issue.
