MolDraw2DQt and MolDraw2DJS don't draw wavy bonds

[greglandrum]

Describe the bug
Wavy bonds are ignored by MolDraw2DQt

To Reproduce

  {
    auto mol = "CC=CC"_smiles;
    REQUIRE(mol);
    mol->getBondWithIdx(1)->setStereoAtoms(0, 3);
    mol->getBondWithIdx(1)->setStereo(Bond::BondStereo::STEREOANY);
    bool kekulize = true;
    bool addChiralHs = true;
    bool wedgeBonds = true;
    bool forceCoords = true;
    bool wavyBonds = true;
    MolDraw2DUtils::prepareMolForDrawing(*mol, kekulize, addChiralHs,
                                         wedgeBonds, forceCoords, wavyBonds);
    CHECK(mol->getBondWithIdx(0)->getBondDir() == Bond::BondDir::UNKNOWN);
    CHECK(mol->getBondWithIdx(1)->getStereo() == Bond::BondStereo::STEREONONE);

    {
      QImage qimg(400, 400, QImage::Format_ARGB32);
      QPainter qpt(&qimg);
      MolDraw2DQt drawer(qimg.width(), qimg.height(), &qpt);
      drawer.drawOptions().bondLineWidth = 3;
      drawer.drawOptions().scaleHighlightBondWidth = true;
      drawer.drawMolecule(*mol, "wavy bonds");
      qimg.save("testWavyBonds.qt.1.png");
    }
  }
