Feature/imgproxy builder override

[rtp-cgs]

For readability I created a new pull request, I hope this is ok.
Related Pull Request: #11

As you mentioned in the related pull request I created an interface for the ImgproxyBuilder class allowing to override it by using the Objects.yaml. Additionally I added the ThumbnailConfiguration object to the ImgproxyBuilder and a addProcessingOption allowing to add processing options inside the generateUrl method using this configuration object.

Example how to override the ImgproxyBuilder class:

Classes/ImgproxyBuilder.php:

class ImgproxyBuilder extends ImgproxyBuilderBase
{
    public function generateUrl(ImgproxyUrl $imgproxyUrl): string
    {
        $configuration = $this->thumbnailConfiguration;
        $focusPointX = ObjectAccess::getProperty($configuration, 'focusPointX', true);
        $focusPointY = ObjectAccess::getProperty($configuration, 'focusPointY', true);

        if (is_float($focusPointX) && is_float($focusPointY)) {
            $focusPointX = ($focusPointX + 1) / 2;
            $focusPointY = ($focusPointY + 1) / 2;

            $imgproxyUrl->addProcessingOption('gravity:fp', $focusPointX . ':' . $focusPointY);
        }

        return parent::generateUrl($imgproxyUrl);
    }
}

Configuration/Objects.yaml:

'Networkteam\ImageProxy\ImgproxyBuilderInterface':
  className: Vendor\ImgProxy\ImgproxyBuilder

Please let me know what you think about this, if this meets your expectations I would also add the example to the README file.

Hello @christophlehmann

I would like to use the original package again in our projects, can you give me a rough idea when this could make it to the main branch?
