Helpers to integrate Prismic into Next.js apps

/**
 * Resolves a module's default export. The module may provide its default export as a `default`
 * property on an object. This happens when named and default exports are mixed in modules.
 *
 * In ES Modules, mixing is fine since the module resolver can distinguish default and named
 * exports. In transpiled modules, however, all exports are put into a single object, and the
 * default export is provided at a property called `default`.
 *
 * This helper is needed by Next.js uses CJS files with named and default exports.
 *
 * This helper _should_ be a temporary hack until Next.js and Node.js resolve their ESM
 * difficulties. This will likely not be removed any time soon, unfortunately.
