Fix #993, which went stale in 2019 and is now reopened. It was not explicitly stated in the documentation, but Xlsx supports hyperlinks when clicking on a drawing. User tried to use the same format for internal hyperlink that is documented for cell internal hyperlink, and that failed (corrupt spreadsheet, hyperlink doesn't work). That was because Xlsx uses `#` rather than `sheet://`. For drawings, Xlsx Writer will now automatically convert `sheet://` to `#`, and Xlsx Reader will now convert the other way. No change is needed for cell hyperlinks. Documentation is now updated, including a statement that drawing hyperlinks work only for Xlsx.
