A binary blob of writer-specific data. This data typically consists of types that are
unavailable to Calc (e.g. SwFmtVertOrient), or that Calc doesn't care about.

@remarks Note that in autoformat versions prior to AUTOFORMAT_DATA_ID_31005, Calc
logic handled and stored several writer-specific items (such as ScAutoFormatDataField::aAdjust).
That logic was preserved. From _31005 onward, writer-specific data should be handled by
blobs to avoid needlessly complicating the Calc logic.
