While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
* Recognize 'Hidden' Attribute in Xml Spreadsheet
Fix#3566; PhpSpreadsheet should now handle Hidden attribute for rows and columns in Xml spreadsheets. Also added the ability to load Xml spreadsheet from string rather than file, as can be done for Csv and Html.
* Add Support for Top Left Cell
Another missing piece.
* Font Bold/Italic
Was always setting to true rather than checking value for 0/1.
* Active Sheet Index
Had always been set to hard-coded 0. Read it from XML if available.
* Selected Cells
Get Selected Cells from XML when available.
* Worksheet Protection and Style Protection
Add support for those to Xml Reader.
* Column Spans
Not really an essential part of Excel, used in Xml to reduce file size.
