blazy 8.x-1.0-beta6

A few notable changes:

• #2838213: Use vanilla JS.
• Decoupled Views stuffs from Blazy into BlazyViews.
• Simplified media switch player JS.
• Fixed for schema error with double and float insanity at sub-modules.
• Simplified Blazy::buildUrl() to remove image_style $modifier assumption, and let the actual extender use regular image_style override instead. GridStack and Mason should update this accordingly.
• Added Media switcher "Image rendered by its formatter" option to render images as is for a special formatter with fieldable entities like Media, or Paragraphs formatters such as with Image Link Formatter.
• Refined select #options conditions.
• Removed some complex form states to use custom JS with CSS visibility instead.
• Allowed disabling Aspect ratio option which is not relevant for fixed grids like Mason or GridStack. Also image_style option such as with GridStack multi-image-style grids field formatters.
• Decoupled iframe related attributes into Blazy::buildIframeAttributes().
• #2834759: Allow missing image.
• Decoupled base entity reference formatter without field supports into \Drupal\blazy\Dejavu\BlazyEntityBase to allow a simple ER formatter.
• Added form--style- classes for easy decluterring of Blazy/ Slick form which is not easy with form states.
• Changed library weights.
• Moved Colorbox mobile dimension check outside the loop.
• Updated blazy.admin.js to declutter options which are not properly managed by form states.
