 * Class AssetResolver
 *
 * This utility class resolves URIs to built assets in the /dist directory of our theme. Built assets have a version
 * hash within their file name – each time the file changes, this hash will change which changes the file name.
 *
 * This class provides the functionality to resolve the file name using the generated manifest at
 * /dist/mix-manifest.json without having to specify the version hash.
