This method returns a list of URLs to precache, referred to as a "precache
manifest", along with details about the number of entries and their size,
based on the options you provide.

@param {Object} config Please refer to the
[configuration guide](https://developers.google.com/web/tools/workbox/modules/workbox-build#getmanifest_mode).
@return {Promise<{manifestEntries: Array<ManifestEntry>,
count: number, size: number, warnings: Array<string>}>} A promise that
resolves once the precache manifest is determined. The `size` property
contains the aggregate size of all the precached entries, in bytes, the
`count` property contains the total number of precached entries, and the
`manifestEntries` property contains all the `ManifestEntry` items. Any
non-fatal warning messages will be returned via `warnings`.
