Supports for `router.refresh`, `router.replace`, `router.back`, and `router.forward` (only `router.push` is handled today)

Hey guys, what a great package!

I find it great that nextjs-toploader supports the Next.js push router, because modern Next.js apps use the router API frequently, and I suggest extending the support to include all Next.js router API, especially router.replace() (for query-param updates) and router.replace() for auth redirects.

Without loader support, the UX feels inconsistent, and developers do workarounds.

I’m happy to open a PR with the changes, just let me know!
I think supporting other router API will be by listening to all router navigation methods and firing the same start / complete handlers used for push.
