Add styles options about crexcel

[vectorselector]

I see where you define the styles.xml in archive_builder.init_style. What I wonder is: where are you assigning these defaults and where are you emitting the "t" element for the final sharedStrings.xml file?

<sst xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" count="27" uniqueCount="27">
	<si><t>

and I wonder about emitting either an "s" attribute for each "t" or how the "cell" is defined or emitted as xml builder element.

If I can help you somehow, tell me please. I am a perpetual noob but I like your shard.
