Add router-plugin for bun bundler

[stregouet]

What do you think adding a new router-plugin for bun bundler?
Current plugins seem based on unplugin, since v3 unplugin has added support for bun unjs/unplugin#539 so it should be not so complicated to add support for bun.
If you think it is a good idea I can try submitting a pull request!

I am unable to create a PR as I am not flagged as a collaborator on the project. That said I have pushed up a fix here that is ready to be PRed, reviewed, and merged.
