imagekit-nodjs breaks Nextjs (typescript) build

[vnugent]

I've just added imagekit-nodejs to my Nextjs project, and couldn't get the build to run.

./node_modules/imagekit/libs/interfaces/index.ts:18:3
Type error: Re-exporting a type when the '--isolatedModules' flag is provided requires using 'export type'.

  16 |
  17 | export {
> 18 |   ImageKitOptions,
     |   ^
  19 |   Transformation,
  20 |   TransformationPosition,
  21 |   UploadOptions,
error Command failed with exit code 1.

The build works if I manually add type to the 2 exports in node_modules/imagekit/libs/interfaces/index.ts
