Story #1183: Magento extracts image meta data from file

Description

The Magento\MediaGalleryMetadata module should be created in adobe-stock-integration repository.
The Magento\MediaGalleryMetadataApi module should be created in adobe-stock-integration repository.
The Magento\MediaGalleryMetadataApi\Model\ReadMetadataInterface should be introduced declaring the only method execute(string $content): array
The Magento\MediaGalleryMetadata\Model\Read\Iptc class should be introduced implementing the Magento\MediaGalleryMetadataApi\Model\ReadMetadataInterface
The implementation of execute method should extract iptc metadata from the passed image file content.

Reading iptc metadata example:

$iptcHeaders = [
    'title' => '2#005',
    'headline' => '2#105',
    'keywords' => '2#025'
];

getimagesize('image.jpg', $info);
$decodedMetadata = iptcparse($info['APP13']);
$keywords = $decodedMetadata[$iptcHeaders['keywords']];
$title = $decodedMetadata[$iptcHeaders['headline']];
