[Feat] Programmatic navigation

[davelsan]

I just found this package and it's working great for my use case (i.e., no network requests between transitions). However, I'd like to be able to also trigger transitions programatically, for example using router.push.

Is this something worth considering for a PR? I created a quick POC, but I'm not a Next.js expert by any means, so I'd love to get some feedback.

See #18 for the PR / branch with the example.
