Add setCellVerticalAlignment() & allow setShouldWrapText() to be explicitly set as false

[jonnott]

Fixes issues: https://github.com/box/spout/issues/829 https://github.com/box/spout/issues/737

• add Common\Entity\Style\CellVerticalAlignment
• duplicate get/set/hasSet/shouldApply methods for CellAlignment in Common\Entity\Style\Style for CellVerticalAlignment instead, plus corresponding properties
• add setCellVerticalAlignment method to Common\Creator\Style\StyleBuilder
• add vertical alignment to StyleMerger:: mergeCellProperties()
• adjust wrapText logic in mergeCellProperties() to fix issue https://github.com/box/spout/issues/829
• apply vertical cell styling for both XLSX and ODS, via corresponding StyleManager classes
• transform vertical alignment ‘center’ to ‘middle’ for ODS
• fix logic around wrapText such that the choice whether to include wrapping styles depends on hasSetWrapText() being true, and then use shouldWrapText() thereafter to either set wrapping or no wrapping (for XLSX, wrapText=“1” or wrapText=“0”, for ODS, wrap-option=wrap or wrap-option=no-wrap). previously there was no way to set wrapping to be OFF, only to set it to be ON.
• add new tests to ensure shouldWrapText(false) results in the correct negated wrapText (XLSX) / wrap-option (ODS) styles
• add new tests to StyleBuilderTest for vertical alignment
• add vertical alignment to documentation.md

@adrilo Do you see any outstanding issues with this still preventing a merge?

[jonnott]

Anyone know if there's any likelihood that this will get merged any time soon? Or do I need to submit this PR to openspout/openspout and look to use that in my project instead?
