No "exports" main defined when upgrading to v3.0.0

[conorfuller]

Hello!

First and foremost, thank you for the awesome library - we've been using it for a few weeks now and are very impressed with the results. We attempted to upgrade to the latest 3.0.0 version today however, and we're now getting:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /Users/conorfu/....../node_modules/file-system-cache/package.json [Storefront Client] at new NodeError (node:internal/errors:405:5) [Storefront Client] at exportsNotFound (node:internal/modules/esm/resolve:259:10) [Storefront Client] at packageExportsResolve (node:internal/modules/esm/resolve:533:13)

This is a Node 20/Next 14 based application and we are using a commonjs environment and am unable to switch easily to use ESM. Is it possible to add default exports to the package.json for increased module support?
