Set base_path at runtime?

Feature Request

It would be great if base_path could be set at runtime. People deploy at different sub-paths, and I want to distribute a single binary for all of them.

Implement Suggestion

I suggest adding an argument to router function:

dioxus/packages/fullstack-server/src/launch.rs

Lines 96 to 104 in 417bf7a

	pub fn router(app: fn() -> Element) -> Router {
	let cfg = ServeConfig::new();
	apply_base_path(
	Router::new().serve_dioxus_application(cfg.clone(), app),
	app,
	cfg,
	base_path().map(|s| s.to_string()),
	)
	}

Like this:

pub fn router(app: fn() -> Element, base_path: Option<String>) -> Router {
    let cfg = ServeConfig::new();
    apply_base_path(
        Router::new().serve_dioxus_application(cfg.clone(), app),
        app,
        cfg,
        base_path.unwrap_or(base_path().map(|s| s.to_string())),
    )
}

But this might be too breaking, and impact many people who doesn't need base_path.
