/**
* Creates resized thumbnail images for a given source image in various sizes.
*
* Supports multiple image formats using the GD library. If the image format is AVIF,
* it delegates processing to the handleAvifImage() method which supports both GD and Imagick.
*
* @param string $src Full path to the source image file.
* @param array $sizes Array of target sizes. Each element should be an array [width, height].
* @param string $folder Destination folder for storing generated thumbnails.
* @param string $base_name Base name for the generated thumbnail files (without extension).
* @param string $ext Extension/format of the image (e.g., 'jpg', 'png', 'avif', etc.)
*
* @return array|false Returns an associative array of thumbnail paths on success.
* Keys are the same as in the $sizes array. On failure, returns false.
*
* @throws Exception If an image cannot be created or resized due to an unsupported type or a GD/Imagick error.
