Serve: Add support for 'basepath' option

[wilsonpage]

As per nws docs

If you want all requests to resolve to a base path (i.e. http://localhost:3030/basepath) without having to place all files into a src/basepath sub-directory, use the -b flag:

nws -b basepath

This means allows you to mount the server on different path contexts.

Thanks for the effort you've put into researching this, but I think the project is already way too complex. In turn, I don't think it's good idea to support such an edge case.

I hope you understand that! 😊

Hi leo, can you document how to implement this using rewrites or redirects? It seems like it should be straightforward to do so but I haven't been able to do it correctly.
