Add option for the original size of the image

[linkrb]

We should be able to pass an option to put the original size in the sizes attribute.

Example :

umanit_image_figure_lazy_load(
      image.path,
      'small_thumbnail',         
      'tiny_thumbnail',
      ['thumbnail', 'large_thumbnail'],
      'image alt',
      'img img--cover img--zoom',
      'original',    <-    pass the original size
      'class-figure',
      'Figcaption text',
      'class-figcaption',
      'low'  
    )

When the 'original' size is requested we should insert the following pattern :

sizes= "(max-width: [image width]) 100vw, [image width]"

We also need to implement security for a maximum size (When a customer uploads an image that is too big for example).

umanit_twig_image:
    use_liip_default_image: false
    class_selector: lazy
    placeholder_class_selector: lazy-placeholder
    blur_class_selector: lazy-blur
    max_size: 1600px

If an image is requested with a larger width the pattern become :

sizes= "(max-width: [image parameter max width]) 100vw, [image parameter max width]"
