I'm using the `\PhpOffice\PhpWord\TemplateProcessor` to parse Docx files, but I need to inject HTML into these. Obviously I can't put the HTML directly into that, so I need to convert it to OOXML. 

`\PhpOffice\PhpWord\PhpWord` has the option to: `\PhpOffice\PhpWord\Shared\Html::addHtml($section, $html);`, which injects the converted OOXML into the document, but this doesn't work with the `TemplateProcessor`.

How can I convert the HTML to OOXML when using the `TemplateProcessor`? I've looked through the code, but can't find anything.
