* Add image formats * Add new media top-level object to README * Chromium unshipped JPEG XL * Remove GIF animation (same support as parent) * Add HEIC/HEIF bugs * Rename HEIC to HEIF * Refine Safari data for AVIF * Safari doesn't support JPEG XL with animated images * Add Edge/IE image format data * Add WebP subfeatures * Refine Opera data for WebP * Move {media.formats => media-types}.image * Split media-types/image.json Ran `npm run split media-types/image.json`. * Add spec url for BMP (Bitmap file) * Add media-types to code snippets, generate-types, data-folders * Fix accidental "false" string * refactor: rename {media-types => mediatypes} Avoids dash in TypeScript definitions. * Fix some media-types versions * Fix notes array with single note * Fix spec URL * Add missing WebView entries for media types * Fix AVIF animation version for Edge * Add fragments to media types spec URLs * Add spec URL exceptions for media types * Replace APNG spec URL * Apply suggestions from code review Co-authored-by: Daniel D.
