Describe the bug
When setting up the project as described in the Readme (onto a SvelteKit app), the application will not execute if the svelte config specifies an alternate base path:

svelte.config.js:

import adapter from '@sveltejs/adapter-auto';

/** @type {import('@sveltejs/kit').Config} */
const config = {
	kit: {
		adapter: adapter(),
		paths: {
			base: '/subfolder'
		}
	}
};

export default config;

To Reproduce
Steps to reproduce the behavior:

1. Create new SvelteKit project via 'npm create svelte@latest '
2. Modify svelte.config.js as shown above (just set a base path).
3. Follow steps as descibed in Readme to setup vite-plugin-rsw and create the default crate
4. Start dev server with 'npm run dev'

Expected behavior
The dev server should correctly resolve the WASM module to its actual location; not adjusted by base path.

Screenshots
Not a screen shot, but here's the error I'm getting:

[1] Failed to load url /rsw-hello/pkg/rsw_hello.js (resolved id: D:/Git/demo-wasm/rsw-hello/pkg/rsw_hello.js). Does the file exist?

Note that the two URLs at the top (D:/Git/demo-wasm/rsw-hello/pkg/rsw_hello.js) are actually correct, and I've confirmed that the files actually are there.
