     * When using the `esmExternals` option, this will also apply to external
     * modules. By default, this plugin will render those imports as namespace
     * imports i.e.
     *
     * ```js
     * // input
     * const foo = require('foo');
     *
     * // output
     * import * as foo from 'foo';
     * ```
     *
     * However, there are some situations where this may not be desired.
     * For these situations, you can change Rollup's behaviour either globally or
     * per module. To change it globally, set the `requireReturnsDefault` option
     * to one of the following values:
     *
     * - `false`: This is the default, requiring an ES module returns its
     *   namespace. This is the only option that will also add a marker
     *   `__esModule: true` to the namespace to support interop patterns in
     *   CommonJS modules that are transpiled ES modules.
     * - `"namespace"`: Like `false`, requiring an ES module returns its
     *   namespace, but the plugin does not add the `__esModule` marker and thus
     *   creates more efficient code. For external dependencies when using
     *   `esmExternals: true`, no additional interop code is generated.
     * - `"auto"`: This is complementary to how `output.exports: "auto"` works in
     *   Rollup: If a module has a default export and no named exports, requiring
     *   that module returns the default export. In all other cases, the namespace
     *   is returned. For external dependencies when using `esmExternals: true`, a
     *   corresponding interop helper is added.
     * - `"preferred"`: If a module has a default export, requiring that module
     *   always returns the default export, no matter whether additional named
     *   exports exist. This is similar to how previous versions of this plugin
     *   worked. Again for external dependencies when using `esmExternals: true`,
     *   an interop helper is added.
     * - `true`: This will always try to return the default export on require
     *   without checking if it actually exists. This can throw at build time if
     *   there is no default export. This is how external dependencies are handled
     *   when `esmExternals` is not used. The advantage over the other options is
     *   that, like `false`, this does not add an interop helper for external
     *   dependencies, keeping the code lean.
     *
     * To change this for individual modules, you can supply a function for
     * `requireReturnsDefault` instead. This function will then be called once for
     * each required ES module or external dependency with the corresponding id
     * and allows you to return different values for different modules.
