Replace rollup build for Vite lib mode

[alvarosabu]

Vitejs have a lib mode for build https://vitejs.dev/guide/build.html#library-mode that uses rollup underhood.

//vite.config.ts
export default defineConfig({
    plugins: [vue(), glsl(), vueJsx()],
    build: {
         lib: {
           entry: resolve(__dirname, 'src/index.ts'),
            name: 'lunchboxjs',
            fileName: 'tres',
         },
    },
})

As for demos, check #39

Good catch, thanks! Marking this as lower-priority for now since the dev/build process is working atm, but this is definitely a good candidate for a future fix.
