Buffer not found in static build using sveltekit and Torus library

I need a way to alias Buffer for the browser.

Not sure which module requires this but its probably crypto related.

```
500

Buffer is not defined

@http://localhost:3000/_app/pages/index.svelte-2478ade3.js:1:111754

```

Problem is using Torus node library.

Here is a repo: https://github.com/ralyodio/torus-bufer

```
npm i
npm run build
npm run preview
```

...you will see error. `npm run dev` works fine since node handles requests. Its the browser only environment that is the issue.

The polyfill in `svelte.config.js` appears to not work: https://github.com/ralyodio/torus-bufer/blob/master/svelte.config.js

Reproduce the failure from the linked torus-bufer repository with npm i, npm run build, and npm run preview. Start by reading svelte.config.js and compare the static preview with npm run dev; done means the browser build runs without the Buffer is not defined error.
