/**
 * Webpack projects can have multiple "roots" of `node_modules` that can be
 * the source of installed versions, including things like:
 *
 * - Node library deps: `/PATH/TO/node/v6.5.0/lib`
 * - Monorepo projects: `/PATH/TO/MY_PROJECT/package1`, `/PATH/TO/MY_PROJECT/package2`
 * - ... or the simple version of just one root for a project.
 *
 * The webpack stats object doesn't contain any information about what the root
 * / roots are, so we have to infer it, which we do by pulling apart the paths
 * of each `node_modules` installed module in a source bundle.
 *
 * @param mods {IModule[]} list of modules.
 * @returns {Promise<string[]>} list of package roots.
