Control render using configuration

[BeyondEvil]

Fixes: #239

[Wramberg]

@BeyondEvil As agreed in #239 I gave this a shot. The render is must faster now but unfortunately the collapsed class is misplaced. This means it is no longer possible to unfold the details/extras. With this PR, setting render_collapsed=true yields

<tr>
  <td class="extra collapsed" colspan="4">
    <div>

but it should be

<tr class="collapsed">
  <td class="extra" colspan="4">
    <div>

By changing the implementation to the following it works for me

            if len(cells) > 0:
                tr_class = None
                if self.config.getini("render_collapsed"):
                    tr_class = "collapsed"

                self.row_table = html.tr(cells)
                self.row_extra = html.tr(
                    html.td(self.additional_html, class_="extra", colspan=len(cells)), class_=tr_class
                )

Essentially just moving the collapsed class to the parent html.tr().

lol, awkward.

Good catch! In the end it was good, because I noticed JS needed an update as well to display the correct CSS.
