Loading and editing HEIC/HEIF images

We can use the preprocessImageFile property on the createDefaultImageReader function to add custom image loader logic.

Using a third-party library called heic2any we can add HEIC image support to the editor.

                // If is not of type HEIC we skip the file
                if (!/heic/.test(file.type)) return file;

                // The editor expects a File so let's convert our Blob

    editor.on('process', (imageState) => {
