tdf#159483 sc HTML export: handle data-sheets-value attribute for the text case
HTML pasting "'01" from google sheets to Calc worked already, but
HTML copying from Calc still converted 01 to 1.
What's required is to emit a general marker in the HTML output and then
the correct data-sheets-value attribute on the relevant <td> element.
Add a way to inject a marker in ScHTMLExport::WriteBody() (so
data-sheets-* is considered at all) and extend
ScHTMLExport::WriteCell() to write the data-sheets-value attribute for
the text case as a start.
Other types like booleans are not yet handled at export time.
