"""Generate ``fixtures/xlsx/hyperlink-target-modes--<scheme>.xlsx``.

Parameterised across the 3 external-URL schemes described by
``features/xlsx/hyperlink-target-modes.json``: http, mailto, file-uri.

Each fixture is a one-cell workbook with cell A1 hyperlinked to the
requested URL. This emits a worksheet-level <hyperlinks>/<hyperlink/>
entry plus a sibling <Relationship .../hyperlink TargetMode='External'/>.
