Webpack plugin fails in a fresh Next.js app

[holdenmatt]

Bug Report

I'm trying to use Perspective in a fresh Next.js app, and neither of the documented webpack config options work, so I'm only able to use it in INLINE mode.

I've spent a few hours trying to debug unsuccessfully, so created a clean repo to reproduce the issue.

Steps to Reproduce:

1. Create a fresh Next.JS app using npx create-next-app: https://nextjs.org/docs/api-reference/create-next-app
2. npm install @finos/perspective @finos/perspective-webpack-plugin
3. Add a minimal next.config.js file to add new PerspectivePlugin() as a webpack plugin.

Expected Result:

Perspective should work without errors using the webpack plugin from the documentation.

Actual Result:

I get 404s for psp.async.wasm and perspective.wasm.worker.js and a slew of errors.

Environment:

Additional Context:

I created a clean repo here that reproduces the error:

Appreciate any suggestions or fixes for this.
