/**
 * With ESM it is possible to export both a default value and multiple named exports.
 * With CJS it is possible to "mock" ESM functionality with a `__esModule=true` flag
 * but still only export a single "default" export, or multiple named exports.
 *
 * This helper method detects when a library tries to do a "default" export with other named values
 * and returns the "intended" default value.
 *
 * It also handles CJS exports that export an entire object via `module.exports = {}` rather than export syntax,
 * as well as extracting the `default` (if exists) from a dynamic import.
 *
 * Note there is not "namedExport" equivalent because it is assumed module loaders successfully parse that
 * out for both CJS and ESM.
 *
 * @param {*} mod - "default" export that might be wrapped in another layer
 * @returns {*} unwrapped module
