require call in ESM build of ts-client

[DownChapel]

We're using SvelteKit (which uses Vite) with the @commercetools/ts-client package. When we run the production version of the website it throws the following error when trying to import the package:

ReferenceError: require is not defined in ES module scope, you can use import instead
This file is being treated as an ES module because it has a '.js' file extension and '/app/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

After digging into this a bit the issue appears to be caused by the fact that
the ESM build of ts-client (commercetools-ts-client.esm.js) has a require call in it. E.g. this is how it appears in my node_modules directory:

The buffer package appears to allow using the node buffer module in the browser. We're using the package in node (server-side in SvelteKit), so if I remove the require call everything seems to work fine.

We've managed to work around this by using patch-package, but it doesn't seem correct the ESM file has a require call in it instead of an import statement?

The require call looks to have been added here: #835

Thanks!
