Enable `lazy` loading by default

With the general availability of loading="lazy" in all relevant Browsers we added lazy loading as a default.
While this is definitely the most user friendly default it is not always the best for the site performance.

In general all images that are immediately visible to the user should be loaded via loading="eager" and everything else via loading="lazy".

For Kaleidoscope images or pictures in the site header you can set loading="eager" manually.
For the main content collection we suggest to enable eager loading for the first content in main and lazy load the rest.

renderer = Neos.Neos:ContentCollection {
    nodePath = 'main'

    // configure separate iterator for main content 
    content.iterationName = 'mainContentIterator'

    // enable lazyness for first items
    prototype(Sitegeist.Kaleidoscope:Image) {
        loading = ${mainContentIterator.isFirst ? 'eager' : 'lazy'}
    }
    prototype(Sitegeist.Kaleidoscope:Picture) {
        loading = ${mainContentIterator.isFirst ? 'eager' : 'lazy'}
    }
}

Add Support for Neos 8.0

v6.2.1

TASK: Relax composer dependencies for Neos 8.0

Configure alternate driver and format for dummyImages

Some imagine drivers like vips do not support the creation of images on the fly which breaks the dummy images.
This change allows to configure an alternate driver that is used for the dummyImages plus a fallbackFormat that is used when the chosen
format could not be rendered.

Thanks to @gradinarufelix for providing the PR and to @rolandschuetz and @kdambekalns for testing:

Sitegeist:
  Kaleidoscope:
    dummyImage:
      overrideImagineDriver: 'Imagick'
      fallbackFormat: 'png'

BUGFIX: Remove src attributes from source tag that is technically allowed but ignored inside of picture elements

This is a backport from a bugfix that was merged to 6.1 instead of 6.0. Thank to @kdambekalns for detecting this.

Generic alt and title for Image Sources, no src in source tags, phpstan and no more Neos 4.3 support

Changes;

1. While the source tag allows an src attribute it is ignored in picture tags. Since this is all Kaleidoscope cares about we can remove this safely.

2. The codebase is now tested with phpstan. To do so we had to drop the Neos 4.3 support.

3. All imageSource FusionObjects now support the fusion attributes 'alt' and 'title' that will be used as fallback for the
   respective attributes of the img-tag. That way it is no longer necessary to pass three separate properties around.

Examples:

1. Use title and alternativeText from node properties with fallback to the asset title:

imageSource = Sitegeist.Kaleidoscope:AssetImageSource {
    asset = ${q(node).property('image')}
    title =  ${q(node).property('title') || q(node).property('image').title}
    alt = ${q(node).property('alternativeText')}
}

2. Set alt and title for dummy image source

imageSource = Sitegeist.Kaleidoscope:DummyImageSource {
    alt = 'Alternate assigned to source'
    title = 'Title assigned to source'
}

Fix dummyimages in Neos 7.1 and correct documentation

The bugfix for the documentation was provided by @jonnitto .
This release contains also a correction for the readme that was provided by @freesh

Thank you both.
