A resolved, flattened style for a single cell.
Cells in OOXML reference a style by an integer index into cellXfs; each
<xf> there points at a font / fill / border / number format by further
indices. ExVEx.get_style/3 walks those indirections and returns a single
%ExVEx.Style{} record with the concrete sub-records inline.
