fetch options should be passed on fetching

[Edvinas1122]

consider NextJS fetch

const site_data = await fetchSiteMetadata(
  url,
  { next: { revalidate: 30} }
);

we need to pass caching parameter

could you adjust so that in

const response = await fetch(urlString, {
  signal: controller.signal
  ...options
})

we spread options, and in any sub-fetches also

@Edvinas1122 Thank you for using this package! I published v0.2.0 which supports passing fetch options.

caveats

HTTP requests inside the package probe-image-size which fetch-site-metadata depends on are sent by needle package and therefore we can't pass a options. Perhaps I'll work on this problem in future, by forking probe-image-size or write alternative module by myself.
