sw padded numbering: add ODF filter

ODF allows any string as style:num-format="...", go with "01, 02, 03,
...", because that seems to be consistent with both
DefaultNumberingProvider::makeNumberingIdentifier()'s fallback mechanism
and with OOXML (which uses "001, 002, 003, ..." for the "pad to 3"
case).
