Support <base> HTML tag

The need is to expose the application on a dynamic custom base path.

I tried to use the publicPath / remix-mount-routes stack but the base path is defined at the build time.

Started from the create-remix package:

I tried to configure the application manually with the given configuration:

The idea was to expose the application on the /remix base path.
I can display the page but the loading of the scripts seems to "loop"
