A quick hack solution I came up with today. This isn't pretty in the
slightest and is my first pull request so apologise if I've done it
wrong. I normally work on BitBucket.

Example Usage
------------------

$templateProcessor = new
\PhpOffice\PhpWord\TemplateProcessor('C:\Users\Robert\Desktop\sample.docx');

$templateProcessor->cloneRow('rowValue', 10);
$templateProcessor->setValue('test#1', htmlspecialchars('Text goes
here'));
$templateProcessor->setImageValue('testPhoto#1', 'image3.png',
'my-other-image.jpg');
$templateProcessor->setValue('test#2', htmlspecialchars('Text2 goes
here'));
$templateProcessor->setImageValue('testPhoto#2', 'image4.png',
my-image.jpg');

Image sizes now come from the actual image instead of being hard coded.

$xml may not be created if there isn't any images causing an error.
