soul.sty for strikeout does't work with lualatex

[mako09]

When using pandoc with --pdf-engine=lualatex, an error occurs if strikeout is included.

$ echo '~~打ち消し線~~、それから[下線]{.underline}、さらに==ハイライト==' | pandoc -f markdown+mark --pdf-engine=lualatex -V documentclass=jlreq -o sample.pdf
Error producing PDF.
! Package soul Error: Reconstruction failed.

See the soul package documentation for explanation.

 ...                                              
                                                  
l.59 \st{打ち消し線}

This is because the package soul cannot be used with lualatex.

Would it be possible to modify the default.latex as follows to address this issue?

$if(strikeout)$
$-- also used for underline
\ifLuaTeX
  \usepackage{luacolor}
  \usepackage[soul]{lua-ul}
\else
  \usepackage{soul}
\fi
$endif$

Minor note: soul has worked fine for me in the past, even with lualatex.
I support the change though, as it seems to improve CJK support.
