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.
* Xlsx Writer Honor Alignment in Default Font
Fix#3443. A mysterious implementation by Excel. The style tags have an attribute applyAlignment, which nominally says whether or not the style should use its own Alignment. Except ... Excel ignores that attribute and uses the alignment tag if it is supplied ... and, another mystery, uses not the default style for the spreadsheet if not supplied, but rather uses the default alignment style for all spreadsheets even if the spreadsheet's default style uses a non-default alignment. I am changing Xlsx Writer to generate alignment tag unless the alignment matches both the default alignment for the spreadsheet and the default alignment for all spreadsheets (which I expect to happen most of the time).
* Improve Performance
Also don't change horizontal/vertical on Xlsx Read if they aren't explicitly set.
